Structural, mechanical, and tribological properties of CrCN coatings obtained by cathodic arc physical vapour deposition technology at different CH4/N2 gas ratio
Original language description
Chromium carbonitride coatings were deposited by cathodic arc physical vapor deposition technology at atemperature of 300 ?C, as were used the reactive gasses CH4 and N2. The structural analysis of the CrN coatingshowed a polycrystalline structure with mixed CrN and Cr2N phases. All studied coatings, including the CrCexhibits fcc structure. The phases were confirmed by X-ray photoelectron spectroscopy measurements where asurface oxidation was also detected. The increase of the CH4 gas flow during the deposition process leads to aparabolic trend with the highest hardness of 33.5 GPa for the coating deposited at CH4 / N2 = 0.53. At the sametime the lowest coefficient of friction for both counterparts Al2O3 and ZrO2 (0.28 and 0.26, respectively) weremeasured at CH4 / N2 = 1.86. The tribological tests reveal that the wear of the coatings increases with anincreasing CH4 flow rate, whereas the coefficient of friction decreases. This observed contradiction is explainedby a phenomenon described as the effect of Rebinder.
