采用固相团聚法 (SIM )在喷焊粉末中添加稀土 ,解决了因密度不同造成的喷焊层成分偏析的问题 ,从而使组织细小、均匀 ,硬度、耐磨性和抗热疲劳性能均有所提高 ,且喷焊粉具有良好的工艺性能。
Solid phase agglomeration (SIM) is used to add rare earth in spray powder, which solves the problem of composition segregation of spray coating caused by different density, so that the structure is small, uniform, hardness, wear resistance and thermal fatigue resistance Improve, and spray powder has good process performance.
