MULTILAYER COATED WEAR-RESISTANT MEMBER AND METHOD FOR MAKING THE SAME

摘要

A coated wear-resistant member, as well as a method for making the same, includes a substrate and a coating scheme. The coating scheme has a region of alternating coating sublayers. One coating sublayer is Ti x Al y Si100-x-y N wherein 40 atomic percent <= x <=80 atomic percent; 15 atomic percent <= y <= 55 atomic percent; 4 atomic percent <= 100-x-y <= 15 atomic percent. The other coating sublayer is Ti p Al 100-p N wherein 45 atomic percent <=p<=100 atomic percent. The method for making a coated wear-resistant member includes the steps of providing the substrate, and depositing the region of alternating coating sublayers.
