采用钛合金作为重要机器零件的主要原因是其耐蚀性、高强度和低密度。但在生产中存在钛合金的精加工问题 ,因为它们有粘附倾向 ,对加工质量和生产率起负面影响。采用表面塑性变形法加工作为终加工工序 ,不仅可减小表面粗糙度 ,而且还可强化零件的表面层。对于钛合金 ,可采用滚 The main reason for using titanium as an important machine part is its corrosion resistance, high strength and low density. However, there is a problem with the finishing of titanium alloys in production because of their tendency to stick, negatively affecting the quality and productivity of the process. The use of surface plastic deformation machining as the final processing steps, not only can reduce the surface roughness, but also to strengthen the surface layer of the parts. For titanium, roll can be used
