摘要：

To improve the mechanical properties and wear resistance of TiAlN coatings, TiAlCrN coatings with various Cr contents were deposited on 316 L stainless steel via cathodic arc technology. The effect of Cr doping on the microstructure and mechanical properties of the coatings was investigated, and the wear mechanism of the coatings was also revealed. The results showed that TiAlCrN coatings had cubic structure and grew along the (200), (111), (220), and (311) crystal planes. Besides, the texture coefficient of the grains along the (111) crystal plane increased with the Cr target current, namely, Cr doping could promote the optimal growth of the coating along (111) crystal surface. As the Cr target current raised, the hardness and bonding force of TiAlCrN coatings were enhanced, but the coefficient of friction and wear rate of TiAlCrN coatings were decreased. The coating with a Cr target current of 150 A showed the maximum hardness (25. 50 GPa) and bonding force (26. 97 N), as well as the lowest friction coefficient (0. 26) and wear rate (1. 87× 10-5 mm3·N-1·m-1). The main wear mechanisms of TiAlCrN coatings were abrasive, oxidative, and adhesive wear. Meanwhile, TiAlCrN coatings with high Cr target current exhibited a relatively low wear rate, because CrOx with better lubrication properties, was preferentially formed over TiOx and AlOx during the friction wear process. Moreover, Cr doping could effectively ameliorate the spalling phenomenon, thus further strengthening the mechanical and friction wear performance of TiAlCrN coatings. © 2024 Cailiao Daobaoshe/ Materials Review.
