Wear Mechanism of Cemented Carbide Tool in High Speed Machining Titanium Alloy (Ti-6Al-4V)
高速车削钛合金的硬质合金刀具磨损机理研究

Cemented carbide tool was used to turn titanium alloys(Ti-6Al-4V) at high-speed under dry cutting condition.Wear images of cutting tool was observed by SEM,and element distribution of tool surface was analyzed by EDS.Adhesive wear,oxidation wear and diffusion wear were the main wear mechanisms of the cemented carbide tool.Oxidation wear appeared at the wear edge of rake face and flank face of cutting tool.During turning,the cutting temperature of rake face was higher than that of flank face,so adhesive wear...
