摘要：
An improved coated hard alloy tool having a substrate made of a hard alloy, and a multi-layer ceramic coating film provided on the surface of the substrate, the coating film including at least one oxide layer. The top several layers of the coating film are missing partially or completely in an area where the tool is brought into frictional contact with a workpiece. At least one oxide layer (such as Al.sub.2 O.sub.3 layer) is included in the missing layers. This increases wear resistance of the coated hard alloy tool.
