CERTESS ® DT Physical Vapor Deposition PVD Coating

CERTESS DT is an excellent coating for precision
wear components and decorative + functional
finishes on armaments.

CERTESS DT is a lubricious multilayer coating applied by a combination of PVD and PECVD (plasma-enhanced chemical vapor deposition), utilizing HEF's proprietary CAM technology. This coating is a metal (tungsten) doped amorphous carbon-hydrogen coating. The layers are deposited with no significant effect on surface geometry or part dimensions.

CERTESS DT films are tribological coatings that are ideally suited for applications that require a moderate degree of abrasion resistance, reduced adhesive wear (anti-seizure & anti-scuffing properties) coupled with friction reduction – medium load gears, roller bearings, molds & dies, dry or semi-dry punching & forming, armaments. Temperature resistance is up to 300°C. Deposited films are 2 to 4 μm, tailored to the application; hardness ranges from 1200 to 1400 HV and Young's modulus in the range of 120-130 GPa.
