摘要
为了解决装备核心零部件因磨损、消除腐蚀等带来的尺寸超差问题,制作超音速火焰喷涂316L不锈钢涂层性能试样,对试样涂层的形貌、硬度、耐蚀性开展试验检测研究。结果表明,涂层具有与25Cr3MoA接近的硬度和比30CrMnSiNi2A更好的耐蚀性能。由此,提出采用超音速火焰喷涂316L不锈钢涂层进行零件尺寸修复,制定了可行的修理方案和技术路线,确定了修理工序和参数,形成了相关技术文件,用于指导零件尺寸修复,并在油泵轴和肩轴两类零件上成功应用和装机验证,其性能良好,质量安全。
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.
