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。
The microstructures and wear resistance of Ni-based self-fluxing alloy powder sprayed coatings were studied by metallographic analysis, tensile, shear and wear tests. The helical wear parts of the vacuum clay machine were sprayed and strengthened Spiral working life increased by 5 times.
