| Abstract: | In order to solve the problems of dimension deviation caused by wear and corrosion of core parts of equipment,the high velocity oxygen fuel(HVOF)316L stainless steel coating performance samples were made,and the morphology,hardness and corrosion resistance of the coatings were tested. The results showed that the coating had a hardness close to that of 25Cr3MoA and better corrosion resistance than 30CrMnSiNi2A. Therefore,the HVOF 316L stainless steel coating was used for part size repair,a feasible repair plan and technical route were developed,the repair process and parameters were determined,and the relevant technical documents was formed to guide the part size repair which had been successfully applied and verified on oil pump shaft and shoulder shaft with good performance and safe quality. |
