WIPO Patent Application WO/2023/162683
Kind Code:
A1
Abstract:
A coated tool according to the present disclosure has a substrate conaining a hard phase and a joining phase, and has a coating layer. The coating layer includes an adhesive layer and a wear-resistant layer. The adhesive layer contains TixAlyMz (M is at least one metal selected from among Si and elements in groups 4a, 5a, and 6a of the periodic table, and the atomic ratios for all elements are such that 40 ≤ x ≤ 80 and 0 ≤ y ≤ 55, where x + y + z = 100). The wear-resistant layer contains TiaAlbCrcMd (M is at least one metal selected from Si and elements in groups 4a, 5a, and 6a of the periodic table (excluding Cr), and the atomic ratios of all elements are such that 15 ≤ a ≤ 40, 55 ≤ b ≤ 75, 10 ≤ c ≤ 20, and 0 ≤ d ≤ 15, where a + b + c + d = 100).
