Abstract
TiN-Cu metal-ceramic coatings grown by vacuum arc PVD and containing 0–20 at % copper consist of titanium nitride and copper, which is X-ray amorphous up to 10 at % Cu. The presence of copper in the coatings reduces the crystallite size of the nitride phase from 100 to 20 nm. The hardness of the coatings increases from 20 to 49 GPa as the copper content of the coatings increases to 3.5 at %. Further increase in copper content, up to 20 at %, accompanied by a decrease in the crystallite size of the nitride phase, leads to a drop in hardness to 14–15 GPa, which is caused by the effect of the soft, plastic metal and porosity. We have studied the tribological and adhesive-cohesive properties of the coatings grown on hard-alloy substrates.
