HARD COATING HAVING EXCELLENT WEAR RESISTANCE AND OXIDATION RESISTANCE AND TARGET FOR FORMING THE SAME, AND HARD COATING HAVING EXCELLENT HIGH-TEMPERATURE LUBRICATING ABILITY AND WEAR RESISTANCE AND TARGET FOR FORMING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a hard coating which has oxidation resistance and wear resistance more excellent than those of the conventional coating.;SOLUTION: The hard coating is composed of (Al_a, M_b, Cr_1-a-b)(C_1-eN_e)(wherein, M is W and/or Mo), and 0.25≤a≤0.65, 0.05≤b≤0.35 and 0.5≤e≤1 are satisfied (a, b and e respectively denote the atomic ratios of Al, M and N).;COPYRIGHT: (C)2011,JPO&INPIT
