How about DLC-Diamond Like Carbon Coating

Diamond-like carbon (DLC) coatings are thin layers of carbon-based materials that have some of the unique properties of diamond. DLC coatings are often applied to metallic surfaces to improve their wear resistance, reduce friction, and protect against corrosion.

DLC coatings can be applied using a variety of methods, including chemical vapor deposition (CVD), physical vapor deposition (PVD), and ion beam deposition. The specific method used depends on the desired properties of the coating and the type of substrate being coated.

DLC coatings are known for their excellent hardness, wear resistance, and low friction coefficient. They are often used in applications where these properties are important, such as in the aerospace, automotive, and medical industries. DLC coatings can also be used to improve the performance of cutting tools, machine parts, and other components that are subjected to high levels of wear and tear.

SYSTEM SUMMARY

Diamond-like-Carbon coatings are high performing and easy operating, equipped with arc sputtering system, which are used in demanding automotive, non-ferrous material machining and industrial engineering environments where component surfaces are subjected to high contact pressure, intermittent lubrication or dry sliding and rolling environments where severe abrasive and adhesive wear conditions exist. DLC coatings are also commonly applied onto various medical and dental instruments and implants to provide a dark black, anti-reflective and bio-compatible surface with enhanced tribological protection properties.
