Diamond Like Carbon PVD Coating Equipment

Diamond-like-carbon (DLC) vacuum coating machine

Diamond-like-carbon (DLC) coatings are a particular area of PVD coating.  Among PVD & PaCVD coating compositions and technology, DLC coatings stand out as a particularly distinctive category.  These coatings exhibit a desirable combination of a low coefficient of friction and high micro-hardness, making them extremely effective in many tribological and wear applications. 

DLC coatings are formed when ionized and decomposed carbon or hydrocarbon species land on the surface of a substrate with energy typically 10-300eV. DLC films may possess exceptional mechanical (high hardness), optical (high optical band gap), electrical (high electrical resistivity), chemical (inert) and tribological (low friction and wear coefficient) properties and can be deposited at low substrate temperature (<200°C).

Typical Applications for DLC Coatings:
DLC coatings have many potential applications for tribological and wear applications.  Typical areas of utilization for these coatings include:

Specifications

The PVD coating equipment comes with all facilities, control systems and auxiliary appliances for the deposition of many metals on many substrates.

It’s equipped with the newest Ion Bombardment (plasma) option for preparation and pre-treatment of the part to be metalized: through the Ion Bombardment application it is possible to increase the adhesion onto the substrate of the metal deposited. Ion Bombardment process is applied directly in the same cycle of metalizing, before the metal deposition phase. The automation software and the systems guarantee maximum uniformity and quick operation.

1. What is PVD coating?

Physical Vapor Deposition or PVD, is a term used to describe a family of coating processes. The most common of these PVD coating processes are evaporation (typically using cathodic arc or electron beam sources), and sputtering (using magnetic enhanced sources or “magnetrons”, cylindrical or hollow cathode sources).  All of these processes occur in vacuum at working pressure (typically 10-2 to 10-4 mbar) and generally involve bombardment of the substrate to be coated with energetic positively charged ions during the coating process to promote high density. Additionally, reactive gases such as nitrogen, acetylene or oxygen may be introduced into the vacuum chamber during metal deposition to create various compound coating compositions.  The result is a very strong bond between the coating and the tooling substrate and tailored physical, structural and tribological properties of the film.
We are constantly working on improvements to PVD processes and coatings.  We have developed new coating compositions, expanded our family of carbon coating processes (DLC). We are devoted towards maintaining our position as a leader in PVD coating technology.
