摘要： A coated tool includes a base and a coating layer located on the base. The coating layer includes a first layer having a thickness of 1 μm or more located near the base, and a second layer including Al2O3 particles which is in contact with the first layer and is located more away from the base than the first layer. A difference (A2−A1) between an erosion ratio A2 in the second layer and an erosion ratio A1 in the first layer is 0.60 to −0.30 μm/g. The erosion ratio is obtained by collision of a liquid A in which 3 mass % of spherical Al2O3 particles having a mean particle diameter of 1.1-1.3 μm is dispersed in pure water. A cutting tool includes a holder which includes a pocket, and the coated tool located in the pocket.

摘要： Provided is an alloy material including a metal oxide thin layer that can be formed using a simple method at low cost and can further suppress volatilization of Cr, which causes deterioration of a fuel cell, compared with a case where conventional expensive materials are used. Disclosed is a manufacturing method for an alloy material including a coating treatment step for coating a substrate made of a Fe—Cr based alloy with Co, and an oxidation treatment step for performing oxidation treatment on the substrate in a moisture-containing atmosphere after the coating treatment step.

摘要： A coated cutting tool includes a substrate and a hard coating film. The hard coating film includes a b layer which is disposed on the substrate, a c layer which is a multilayer coating film laminated on the b layer and in which a c1 layer of a nitride or a carbonitride containing Al and Cr and a c2 layer of a nitride or a carbonitride containing Ti and Si are alternately laminated with a film thickness of 50 nm or less, respectively, and a d layer which is disposed on the c layer and is a nitride or a carbonitride of TiSi. The c layer contains 0.10 atomic % or less of Ar with respect to a total amount of a metal (including metalloid) element and a non-metal element.
