Abstract: A coating material has a first layer deposited on a base material and a second layer deposited on the first layer. The first layer is made of a Ni-base alloy or a Co-base alloy containing carbon as an unavoidable impurity. The second layer is made of a hard material containing carbide and a metal component. The first layer serves as a barrier for preventing carbon from being diffused from the second layer into the base material to prevent the base material from being carburized.
