| Abstract: | Ni60 self-melting alloy powder was spray-welded to make the Ni-based alloy layers by two-step method oxy-acetylene flame spray-welding on the substrate of a special use plunger piston of a certain chemical plant.The technological test and hardness test of the layers have been studied. The result showed that: the hardness of the alloy layers is significantly increased,the technology can meet the requirements of restoration and intensification of plunger piston with high quality and low cost,and this techniqu... |
