With a strong reputation in automotive coating and our REACH-compliant decorative CERTESS Carbon - Tribological coatings Modern and future internal combustion engines generate new issues to solve. Oils and additive packages, components size and surface finish, contact pressure and velocity bring new challenges for surface treatments and coatings. For decades, the performance of tribological coatings has been studied with the goal of developing practical surface treatments to enhance the friction and wear performance of mechanical components. Known parameters that affect coating performance include contact pressure, rolling velocity, sliding velocity, lubricant film thickness, and surface roughness. In the bulk form, polymers may show lower dimensional stability because of high thermal expansion as the local temperature and the frictional contacts in the bulk polymers may be higher due to low dissipation of heat as compared to the thin polymer coatings.

Tribological dry coating is a system solution for mechanically stressed fastening elements and components, such as screws, nuts and washers. The coating is a non-electrolytically applied thin layer with integrated lubrication properties and additional corrosion protection. The use of hard thin coatings on softer substrate materials is very popular in many tribological applications. The hard coating can provide good wear protection and, with a suitable choice of material and surface layer design, the friction can also be low, against an appropriate counterface. Tribological and Functional Coatings publications One of the keys to reducing friction and protecting against wear is to coat components with diamond-like carbon (DLC) or hydrocarbon layers.
