Abstract
A coated tool includes a base and a coating film on the base. The coating film includes an AlOlayer, and a surface layer on the AlOlayer. The surface layer has a first erosion rate of 0.1 μm/min or less. The first erosion rate is obtained from measurement by causing a liquid A, in which 3 mass % of amorphous AlOparticles having a mean particle diameter of 1.1-1.3 μm is dispersed in purified water, to collide with the surface layer. The surface layer has a second erosion rate of 2.0 μm/min or more. The second erosion rate is obtained from measurement by causing a liquid B, in which 3 mass % of spherical AlOparticles having a mean particle diameter of 2.8-3.2 μm is dispersed in purified water, to collide with the surface layer.
