Effect of diamond-like carbon coatings alloying with chromium and molybdenum on the lubricating properties of oils during friction in pair with steel

Abstract The results have been presented of an experimental study of the tribological behavior of diamond-like carbon coatings (DLC) doped with chromium and molybdenum obtained by reactive magnetron sputtering. The effect of alloying with these metals on the tribological characteristics of boundary lubrication of a DLC coating/steel contact has been studied for the case of three model lubricants (inactive, surfactant, and chemically active). It has been shown that doping with chromium and molybdenum improves both the tribological characteristics of coatings under dry friction and the lubricating properties of the model oils, while alloying with molybdenum provides lower coefficients of friction and less wear at dry and boundary friction than alloying with chromium.

The results of an experimental study of the tribological characteristics of inactive, surface-active, and chemically active lubricants in the boundary lubrication mode when steel is rubbed against steel with a carbon diamond-like (Cr—DLC)-coating. For comparison, also tested friction in these friction contacts under similar conditions, but without lubricant. The maximum coefficient of friction and maximum wear was obtained by tribological testing of steel on steel. The minimum coefficient of friction was obtained when steel was rubbed against Сr—DLC-coated steel in a surface-active lubricant medium.
