Abstract

This study takes a new look at carbon-based ion-plasma coatings (DLC) deposited on a steel substrate from acetylene and methylsiloxane gas mixture. The most remarkable result to emerge from X-ray photoelectron spectroscopy is a surface-to-substrate decrease in the “diamond” electron configuration of carbon sp3. A set of tribological tests showed a noticeable decrease in the coefficient of friction. Surprisingly, there was no increase in wear resistance when using DLC coatings on the contact surfaces of nitrided nitralloy steel in a loaded friction unit.
