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.
