摘要
通过金相分析，及拉伸、剪切、磨损试验，研究了镍基自熔合金粉末喷焊层的组织结构和耐磨性能，并对真空练泥机螺旋磨损部位进行了喷焊强化，使螺旋的工作寿命提高了５倍。
Through phase analysis,and pull.shear wear test,studies the forms and resistant wear performances of nickel base metal powder spray welding coating. The spirals of thevacuum refining mud machine were strengthened by metal powder array welding. The working life of spirals was increased five times.
