PROBLEM TO BE SOLVED: To improve the hardness (abrasion resistance), oxidation resistance, adhesion to a base material, etc. of a film formed on a cutting tool, a sliding member, a metal working tool, etc., and to balance it. It has stable properties and forms a stable film and improves the life of tools and the like on which the film is formed. An Al x Ti 1-x-y -z M y R z ( where, M is Si, Cr, W, 1 or more elements selected from Mo, R is Y, Ce, La, misch metal, etc. , At least one element selected from the group consisting of rare earth elements of 0.05 ≦ x ≦ 0. 7, 0.02 ≦ y ≦ 0.25, 0.0005 ≦ z ≦ 0. 05), and a wear-resistant AlTi-based alloy hard coating having the same composition. |
