摘　　要：以预扩散合金粉为主要材料研制了一种导卫板堆焊材料,并对某厂轧机导卫板进行了堆焊修复。现场试验表明,预扩散合金粉对导卫板工作层的强度、耐磨性和抗热疲劳性具有重要影响,堆焊件满足了轧机的使用要求。A kind of new surfacing material was developed with pre-diffused alloy powder as main constituent,and the rolling mill guides were repaired.The application test in production line shows that pre-diffused alloy powder has important effect on the strength,ductility and thermal fatigue resistance of the guides.The repaired guides are good enough in service.
