采用化学失重法、电化学方法和原子吸收光谱法研究了紫铜、Cu-Zn-Al形状记忆合金和Cu-Zn-Al合金在模拟宫腔液中的腐蚀行为.结果表明, 模拟宫腔液中紫铜、Cu-Zn-Al形状记忆合金和Cu-Zn-Al合金的腐蚀历程受阴极氧去极化步骤控制.Cu-Zn-Al形状记忆合金和Cu-Zn-Al合金由于铝的表面离子化倾向比锌的大, 优先形成致密坚固的保护性氧化铝膜, 降低了腐蚀速率.在模拟宫腔液中发现Cu-Zn-Al形状记忆合金和Cu-Zn-Al合金发生脱铝腐蚀, Cl-参与腐蚀反应历程, 促进脱铝腐蚀的进行.白蛋白与氧的竞争吸附加速了阳极溶解, 使紫铜、Cu-Zn-Al形状记忆合金和Cu-Zn-Al合金的阳极活性电流密度随白蛋白浓度的上升而增加.
