Notes:
The friction and wear characteristics of a cathodic arc ion-plated CrSiN coating in slidingagainst different counter materials have been investigated under both unlubricated andboundary-lubricated conditions. Under boundary-lubricated conditions, the CrSiN coating exhibits afriction coefficient of 0.12 to 0.20 against a SAE 52100 steel ball and of 0.04 to 0.07 against aCrN-coated steel pin, depending on wear parameters used. The effects of load, temperature andcounter materials on friction and wear of the CrSiN coating were discussed. The worn surfaces andwear debris generated under different wear conditions were examined by means of scanning electronmicroscopy and Raman spectroscopy to identify the tribochemical reaction and phase structuresgenerated during the wear process. Under unlubricated conditions, iron-based oxides formed insliding against a steel ball, while some chromium oxides were identified on worn surfaces of theCrSiN coating in sliding against an alumina ball in air
