Abstract

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 TixAlySi100-x-yN 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 TipAl100-pN 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.
