摘　　要：为提高脱漆效率,常需提高双氧水添加量,在此情况下,易引起钛合金的腐蚀。分别测试不同双氧水添加量(4.5%、9%、13.5%、18%),不同pH(5.0、6.0、7.0、8.0、9.0),不同双氧水分解抑制剂(聚丙烯酰胺、硬脂酸镁、三聚磷酸钠、EDTA-Na2),不同缓蚀剂(EP030、苯并三氮唑、IDS镁、CTAB)配方对钛合金的腐蚀行为。结果表明,双氧水添加量为3%、脱漆剂pH为5~6、A剂和B剂的配比为1∶1时,钛合金腐蚀最小,且脱漆效率满足要求。The paint remover containing benzyl alcohol and hydrogen peroxide is safe and environmental friendly.To improve the paint removing efficiency,it is necessary to increase the amount of hydrogen peroxide.However,it might cause the corrosion of titanium alloys.The effects of different hydrogen peroxide content(e.g.,4.5%,9%,13.5%and 18%),different pH values(e.g.,5.0,6.0,7.0,8.0 and 9.0),different hydrogen peroxide decomposition inhibitors(e.g.,polyacrylamide,magnesium stearate,sodium tripolyphosphate and EDTA-Na2),and different corrosion inhibitor formulations(e.g.,EP030,benzotriazole,IDS magnesium and CTAB)are tested.The results show that the corrosion of titanium alloy is minimum and the paint removing efficiency meet the requirements when the amount of hydrogen peroxide is 3%,the pH of the paint remover is 5-6 and the ratio of A and B agents is 1:1.
