| 摘 要： | 选择橡胶软油箱外层的橡胶材料及防老化涂层材料与7A04 T6包铝及去包铝、7B04 T6包铝及去包铝合金进行接触腐蚀试验。试验结果表明软油箱中对铝合金腐蚀产生直接影响的非金属材料为橡胶防老化涂层,并确定了四种橡胶防老化涂层材料的腐蚀敏感性顺序;通过对橡胶防老化涂层进行的EDS分析以及涂层浸泡液的pH值变化及氯离子含量研究,认为橡胶防老化涂层中对铝合金腐蚀产生影响的主要成分为氯离子和金属氧化物。 |

| Abstract: | The contact corrosion between 7A04-T6 alloy (clad), 7A04-T6 alloy, 7B04-T6 alloy (clad), 7B04-T6 alloy and materials of rubber fuel tank was studied. The result shows that rubber anti-aging coatings have very important effect on aluminum alloy corrosion .The corrosion order of four rubber anti-aging coatings was decided. The chemical composition of rubber anti-aging coatings was analyzed by EDS. Chloride ion concentration and pH of anti-aging coatings immersed solution were studied. The experiment results show that main components of rubber anti-aging coatings which caused aluminum alloy corrosion were chloride ion and metal oxide. |
| Keywords: | aluminum alloy rubber anti-aging coatings corrosion |
