Tungsten carbide coating tool,using the vapor deposition method,coated carbide cutting tools with a thin layer of refractory metal or nonmetallic compound. coating as a chemical barrier and thermal barrier,reducing the diffusion and chemical reaction between carbide cutting tool and workpiece,thus reducing the matrix wear.coated carbide cutting tool with high surface hardness,good wear resistance,chemical stability,heat and oxidation resistance,low coefficient of friction and thermal conductively.increased more than 3-5 times tool life than uncoated carbide cutting tool,improve cutting speed with 20% to 70%,improve machining accuracy with 0.5-1,reduce tool consumption costs with 20% to 50%.
