| 摘 要： | 分析了铝合金三价铬钝化液的钝化机制，研究了复合盐钝化剂用量、钝化处理时间和温度对钝化膜质量的影响。结果表明，经铝合金三价铬钝化液钝化后的试样，其抗腐蚀性能优于铬酸钝化液，可在常温下进行处理，且处理时间较短，有利于减轻铬酸钝化液中六价铬离子对环境的影响。

| Abstract: | The passivation mechanism of trivalent chromium passivator for aluminum alloy has been studied, including additive amount of complex salt passivator, influence of processing time and temperature on the quality of passive film. The test has shown that the samples treated by trivalent chromium passivator has improved anti-corrosion property. The treat process is at room temperature and quite short. The impact on environment can be reduced without hexavalent chromium acid. |
