摘　　要：探讨电弧喷涂工艺参数变化对涂层组织、抗折弯性能的影响。试验结果表明 :电压 34V ,电流 1 50A时 ,涂层的抗折弯性能最佳 ,随着电压和电流的增加 ,抗折弯性能下降 ,涂层扁平粒子流散加剧 ,合金元素烧损加剧。用此工艺参数修复船用不锈钢油冷套 ,加之合理的喷涂工序与材料匹配 。The effects of parameters changes of electric arc spraying technology on coating structure and anti-buckling performance were discussed in this paper. The experimental results show that, anti-buckling performance of coating is best when voltage is 34 V and electric current is 150 A. With the increase of voltage and electric current, the anti-buckling performance decreased, the flat particle flow went up, and alloying element loss increased. A good repairing result was obtained by combining reasonable spraying process and material matching with this parameter in repairing oil cooling set of stainless steel.
