[0002] The tool is prepared by coating a thin layer of refractory metal or non-metallic compound with good wear resistance on the surface of a cemented carbide or high-speed steel substrate with good strength and toughness using a vapor deposition method. The coating acts as a chemical barrier and thermal barrier, reducing the diffusion and chemical reaction between the tool and the workpiece, thereby reducing the wear of the substrate. The coated tool has the characteristics of high surface hardness, good wear resistance, stable chemical properties, heat and oxidation resistance, low friction coefficient and low thermal conductivity.
