摘要
Ti(1-x)Al(x)N (0.25 <= x <= 0.75) coatings were deposited by reactive DC/RF magnetron co-sputtering. The phase structure, microstructure, surface roughness and chemical composition were investigated. The anti-oxidation behavior of coatings at high temperature was also studied. It has been shown that the coatings with high Al content (x >= 0.67) consisted of hexagonal-AlN and cubic-TiAlN phases, while it has cubic-TiAlN phase for the coatings with low Al content (x<0.67). The roughness of surface of coatings was 1.89 similar to 4.80nm and it decreased with increasing the Al content. The thermal-stability of the Ti(1-x)Al(x)N coatings increased with increasing Al content. (C) 2011 Published by Elsevier B.V.
