| Abstract: | Thickening α-Al2O3 coating which structure and surface were optimization designed was prepared on WC-based cutting tool by a composite of medium and high temperature chemical vapor deposition（MHT-CVD）.The microstructure and surface roughness of the coating were studied by scanning electron microscope（SEM）and surfagauge respectively.The properties of the cutting tools were characterized as well.The results show that the WC-based coated-cutting tools by optimization design of coating structure and surface have better surface and higher working durability. |
