How the Quality of DLC Coatings Play a Substantial Role in Today’s Deposition Industry

DLC coatings provide a variety of benefits to technicians that other coating methods don’t.

diamond-like-carbon-applicationsThe application of diamond like carbon, or DLC, coatings has introduced a new way of producing high quality and consistent coatings for a variety of industries. This type of technology allows for deposition in large scale production machines without having to sacrifice film quality.

Systems Breakdown

Today’s technicians prefer a quality vacuum evaporation system that possesses the ability to deposit PVD layers as well as uniform PACVD layers within the same system. Furthermore, this process allows for the transition from PVD layers to DLC layers with ease and prevents any breakdown when it comes to interlayer adhesion. Hands down, excellent adhesions is the primary factor considered when it comes to deposition technology.

Breaking Down the Coating Process

DLC coating beings when a product is placed into a vacuum chamber that has a carousel fixed on the chamber. Once the chamber is completely evacuated, the produce is then preheated to a set temperature that does not exceed 300 F. The process will then transition into the ion etching phase where ions are bombarded onto the substrate followed by a sputter clean to remove the micro oxides. Sputter cleaning is an important aspect of the entire process because it ensures that there will not be any debris or unwarranted particles that are going to be attached onto the product. Once the produce is fully cleaned, the coating process occurs where a dense and smooth amorphous carbon layer is deposited onto the product’s surface. Once the technician checks for quality control and ensures that the substrate is perfectly placed, the deposition process is complete.

Ion Beam Assisted Deposition for Optics

There is a microscopic coating on most eye glass lenses that protects against a number of common hazards. Lenses aren’t just made of non-scratch materials; optical coating systems use chemicals to achieve the desired effect. These processes are used every day in the construction of semi-conductors, where a thin film of highly conductive material is applied directly to silicon circuit boards. The same principles are also used in the manufacture of eye glasses. Today’s glasses are very different from the old glass lenses of yesteryear. With these new scientific processes, the patient gets a quality product that is cheaper and easier to mass produce.

Ion Beam Deposition Process

The ion beam assisted deposition process begins in a sealed chamber, where special chemicals are heated to release particulate matter. The matter floats around the sealed chamber, while air is forced through. A substrate, the material that will receive the coating, is placed inside the sealed chamber. As the air cools the particulates, they settle onto the substrate. This creates a microscopic film that coats the substrate.

Optic Uses

The most common use for Ebeam coating is in the construction of glare-proof lenses. The thin film coating can also protect the user’s eyes from UV lighting. Anyone who has purchased scratch-resistant lenses has also benefitted from this process. Other coatings keep lenses from fogging up on cold days, or provide mirror sheen to the lenses. Dark shades that cover one’s eyes completely, sometimes called “poker glasses,” also rely on this coating but may need several applications to get the desired tint.

Other Processes

Aside from the actual glasses we wear on our faces, the process is used in other devices as well. Imaging technology used to do scans of your eyes requires special coatings. Any lab equipment that requires a semi conductor to function also uses the process to make the material conductive. Lenses that receive a colored tint may also rely on sputtering to apply the thin layer of dye without harming the lens or obscuring one’s vision.

Final Thoughts

Optical coating is an important part of treating patients with serious vision problems. Optical coatings are useful for tinting lenses of a patient who has just had eye surgery, or keeping eye glasses clean and scratch free. Today’s technology also means that patients worry a lot less about daily cleaning, which may have scratched older lenses. Optics have come a long way thanks to sputtering systems.

Semiconductor Metallization Disposition Processes

During the manufacturing of semiconductors, the vacuum metallization process is used to link together circuits. This is done by placing a thin layer of film made from a metal such as aluminum, nickel or gold between the elements of a semiconductor. While the end goal is to create an electrical connection between components, there are different ways to achieve this.

Here is a look at some of the common metallization disposition processes for semiconductors:

Sputtering: A sputter coater places a thin film by bombarding the target material with ions of an inert gas. The gas is introduced into a low-pressure vacuum while an electric field charges the ions and draws them to the target. Sputtering allows for a high level of control over the dispersal of the coating and can be used in almost any semiconductor application.

E-Beam Evaporation: With electron-beam evaporation, a focused blast of electrons heats the target metal. This causes the metal to vaporize, with the particles condensing on the wafers of the semiconductor.

Filament Evaporation: Also called resistive evaporation, this process involves the heating of a filament by thermal resistance. This is typically done in a bell jar or similar device. As the filament heats up, the metal that is to be deposited melts and the filament becomes wet. The metal eventually melts completely and vaporizes, condensing on the target wafer to create the thin film layer.

Flash Evaporation: A ceramic bar that has been heated by thermal resistance is used in flash evaporation. When the bar touches a length of wire, it causes the target metal to evaporate and be deposited onto the semiconductor substrate.

Induction Evaporation: In induction evaporation, metal in a crucible is melted by radiofrequency radiation.

Discover Common Types of Synthetic Turf Grass

Installing synthetic turf grass on your lawn is great landscaping choice for a variety of reasons. It is an environmentally-friendly choice since it doesn’t require regular watering or any fertilizers. It gives your property a healthy, well-kept look without requiring major maintenance and it can save you money in the long run.

But before you put an artificial lawn in your yard, you need to do some research. Not all types of artificial turf are alike. There are factors that will make certain types of turf more appropriate for different uses. You’ll want to read the specifications provided by the artificial grass manufacturer carefully before you make a purchase to ensure that you are getting the right turf for your needs.

Here is a brief overview of some of the most common types of artificial turf materials and what makes them so unique:

Athletic Turf: This is turf that is specifically designed to go on sports playing surfaces for football, soccer, lacrosse and other sports usually played on grass. The pile height is usually two to three inches and has crumbled bits of rubber or silica sand used as infill. These small pellets of infill are easily tracked into a home, so this is not a good residential turf choice.

Landscaping Turf: Turf that is appropriate for residential use has a microfiber layer of yarn that serves as the “roots” of the turf. This layer keeps the blades of turf upright, eliminating the need for infill. This type of grass often has the highest amount of yarn per square foot and is made to closely resemble actual grass.

Pet-Friendly Turf: If you have pets at your home – particularly dogs – you will want to look for artificial turf that is specifically designed for them. This means that it will have a special antibacterial treatment meant to reduce odors associated with urine and feces. It will also have excellent drainage capabilities, making it easy for you to hose down and clean the turf.

Playground Turf: When it comes to turf for playground uses, safety is important. Turf that’s appropriate for the playground is often heavily padded to cushion youngsters who fall while playing rough and tumble. The turf itself is also often very dense. It is possible to use athletic turf as an alternative to playground turf; however, the infill can be messy when little hands and feet are playing on the turf.

Coating Optics with Sputtering Systems

Sputtering systems are created in various configurations, including magnetron sputtering, E-beam evaporation and PVD Thermal Evaporation. Sputtering places extremely thin layers of material onto a target surface. These layers can be measured by the nanometer, and are often so dense that they are almost as hard as diamonds. These layers are so small that you would need an electron microscope to see them.

Healthcare, semi-conductor production, computer components and special optics all make use of sputtering systems. The carbon-like coatings these systems produce protect the target material from heat, pressure and abrasion. In order to prevent a fault in the finished product, it is incredibly important that operators never touch the inside of a vacuum with their bare hands. Skin oils left in the chamber introduce contaminates that alter the hardness of the film.

In any sort of sputter coater system, the gas inside the chamber is heated up to temperatures that are like that of the sun. A state of matter called plasma is created that allows for the greatest freedom of motion in particles. The particles leave the plasma and condense onto the target material in the chamber.

A typical application of a sputter coater system is for optics. Coating optical lenses helps prevent scratching and other defects.

Chinese Manufacturing Records a 14-month high, Reveals HSBC’s Purchasing Managers

Chinese manufacturing records a 14-month high which means that the world’s second-largest economy is showing signs of recovery.
Putting things in perspective in a statement, HSBC analyst, Hongbin Qu, said, “The latest data confirmed that China’s ongoing growth recovery is gaining momentum mainly driven by domestic demand conditions. However, the drop of new export orders and the downside surprise of November exports growth suggest the persisting external headwinds.

This calls for Beijing to keep an accommodative policy stance to counter-balance the external weakness, provided inflation stays benign.” However, the conclusions from this data was based on a preliminary version of the monthly HSBC Purchasing Manager Index where responses from 75 to 80 percent of the 420 companies are compiled. According to this report, the index rose to 50.9 this month which was an increase from November’s 50.5. These gains in December were unexpected considering the weak November trade data that suggested that China economic recovery was shaky. Employment as well as new orders also registered an increase in the report.

Almost all the sub-indexes showed improvement except those related to output and new export orders. New exports order, in particular, took a dive in December registering 2.9 percent annual growth from compared to October’s 11.6 percent. It must be pointed out that the sub-index for employment was the highest it has been since February while the sub-index for new orders showed an increase for the fifth month in a row. A government report also showed that industrial production has risen to an 8 month high while inflation also climbed above 33-month lows. 

High Density Foam Sheets Can Help Fight Back Pain In Your Pets

It is not uncommon for pets to suffer from back pain.  Back pain for a dog or a cat can cause a lot of problems in terms of limiting their range of motion and what they are able to do.  High density foam sheets can go a long way to alleviating a lot of the pain that your dog or cat is going through.

Back problems in dogs or cats can be caused by a wide range of sources.  Your dog or cat may end up with a lot of pain simply because they are going through troubled times with a disease or something of that nature.  It could also be though due to the fact that they are not able to actually sleep well at night.  A dog or cat, just like a human, needs to get his or her rest on a daily basis.  Without that rest they can find themselves in incredible pain each and every day.  Having the right type of sleeping material can go a long way to helping fight the back pain.

There are many different types of beds for cats or dogs.  New technology such as acoustic foam can help make your dog sleep much better,  Foam Canada retailers have some great information out there to help you learn more about these new technology dog beds available.  If you want to learn more and invest in something such as a nice memory foam bed for your cat or dog you should definitely look into canada.foambymail.com

 

What Is The Purpose Of Artificial Grass And Artificial Turf

Article submitted by ArtificialTurfSupply.com

While it’s not common in a lot of low income areas, there is a thing known as artificial grass and artificial turf. So what’s the purpose of these two things and how are they relevant to real grass? Why would you choose it over real grass anyways?

The Purpose

Artificial grass doesn’t need to be cut, it doesn’t need to be watered and it’s for the appeal only. It looks great to other people, so it’s definitely a show and tell kind of thing.

Who Would Use Turf

The main difference between grass and turf is that grass has longer blades and turf is generally flat, almost like carpet. Turf is often used for football fields and other areas where there’s a lot of activity such as running or for other sporting events as well such as soccer. Which one someone would use entirely depends on the situation and what they’ll need it for.

There’s also something known as synthetic turf grass for people who want more realistic looking grass as well. For people who would like to have this kind of grass at their homes, there’s something known as artificial residential turf which allows them to do this. If you’re looking for a supplier of these kind of grass, I personally would recommend artificial turf supply as a provider (everyone will have their different preferences). Also, you’ll have to figure out the dimensions of your yard as well before contacting a supplier.

Overview of Two Kinds of Foam Replacement Types

A lot of people, when they are trying to give new life to their furniture, decide to do foam replacement rather than buying a whole new piece of furniture.  This is a really good way to save some money and not to have to pay a lot of money for a whole new piece of furniture. it also allows the person to keep a piece of furniture that they love but that is losing its firmness.  Below is the information on the common kinds of foam when it comes to replacing foam.

The first thing that you have to do when you are replacing foam in something is to figure out what kind of foam you want.  Common kinds of foam are Polyfoam, or polyurethane, and the polyurethane-rubber mix that’s known as Nimbus.  Nimbus blends rubber and polyester and it’s also used in some of the mattresses. It’s thought to be a really great kind of foam and it’s highly regarded in auto upholstery because it’s soft and durable.  The Polyfoam’s more common in all of the applications because it’s more affordable.   For someone who is looking for a high quality project, a good choice is Nimbus.

There are many sites that you can go in order to find custom foam cushions and dry fast foam.  When you are looking for a dryfast foam supplier, look at their reviews and see what others have said about it.  Then you can base your decision on what they have said about the company.
