Microstructure,oxidation behavior and tribological properties of AlCrN/Cu coatings deposited by a hybrid PVD technique
文献摘要：
Achieving high hardness and low friction at elevated temperatures for nitride-based hard coatings has substantial scientific interest and application significance.In this study,AlCrN/Cu coatings were deposited by a hybrid PVD technique combining arc evaporation from an Al60Cr40 target and magnetron sputtering from a Cu target in a mixed Ar and N2 atmosphere.The microstructure,oxidation behavior,and tribolog-ical properties of the coatings were investigated.AlCrN/Cu coatings show a dual-phase structure of(Al,Cr)N solid solution and Cu metallic phase.Excessive sputtering power of the Cu target induces the disin-tegration of interlayer interfaces of the nano-multilayered geometry,accompanied by a decline in hard-ness from above 30 GPa to 22.7 GPa.Moreover,the formation of fine CuO grains on the coating surface is conducive to reducing the friction coefficient of AlCrN/Cu when exposed to air at high temperatures.The AlCrN/Cu coating with a sputtering power of 0.5 kW obtains a friction coefficient of 0.39±0.05 after pre-oxidation at 800℃,distinctly lower than that of AlCrN,which exhibits a friction coefficient of～0.65.The further transformation of CuO to cubic Cu(Al,Cr)2O4,which stems from the solid-state reaction of CuO,Al2O3,and Cr2O3,would cause a rise in friction coefficient and wear loss.The mechanism of oxi-dation and tribological behavior of the AlCrN/Cu coatings related to the temperature and Cu content was discussed.
