摘　　要：采用多功能表面分析系统对车铣加工Ti6Al4V钛合金的硬质合金刀具进行X射线电子能谱分析(XPS)。通过对磨损区域进行全谱扫描和精细谱扫描,应用XPSPEAK4.1和Origin7.5对所得数据进行分峰拟合处理,最后分析了所生成的氧化物对刀具磨损和刀具寿命的影响。试验结果表明涂层材质为S30T的刀具磨损表面有Ti O_2、Al_2O_3、Co O和Ti N等物质生成;H13A非涂层材质刀具磨损表面有Ti O_2、WO3和Co_3O_4等氧化物生成。The analysis using X-ray Photoelectron Spectroscopy（ XPS） method was applied to cemented carbide tools in turn-milling Ti-6Al-4V titanium alloy. The full and fine spectrum scanning was done on special wear areas,and the data were dealt with XPSPEAK4. 1 and Origin7. 5. Results show that there exist a lot of oxides,such as Ti O2,Al2O3,Co O on the scanned wear surfaces of coated S30 T grade carbide tools and Ti O2,WO3 and Co3O4on uncoated H13 A grade carbide tools.The influence of these oxides on tool wear and life was also analyzed.
