摘　　要：　研究了一种焊接不锈钢的电化学抛光工艺,确定了电化学去氧化铁及电化学抛光液的化学成分和工艺参数为:H3PO4(85%)740～770mL/L,H2SO4(98%)180～210mL/L,CrO350g/L,明胶8～10mL/L,抛光液密度1.70～1.78g/cm3,温度55～65℃,JA=35～45A/dm2,槽电压10～20V,时间4～5min,阴极为铅板。该工艺不会使不锈钢基体产生点蚀,能使不锈钢表面及焊缝达镜面光亮。Electrochemical polishing of welding stainless steel was studied, and the chemical composition and technological parameters were established for electrochemical clearing of oxide layer and electrochemical polishing. Both the surface of stainless steel and weld joint could reach the bright mirror without pitting.
