摘要：

More and more attention has been paid to AlCrN coatings with self-lubricating property and high temperature oxidation resistance. In this study, the synergy of V and Si on the microstructure, tribological and oxidation properties of AlCrN coatings is investigated in detail. With V is gradually replaced by Si, coatings' microstructures are transformed from compact columnar to coarse columnar, and a dense fine-grained structure, and finally to a featureless dense structure. When the V content is 10 at.%, the coating is consisted of c-VN and c-Al(Cr)N solid solution phases. As decreasing the rati...
