用电沉积方法在316L不锈钢表面制备Co含量为21.9％～34.62％(摩尔分数)的Pd-Co膜层和Cu含量为5％(摩尔分数)的Pd-Cu膜层,通过失重试验、极化曲线以及扫描电子显微镜等方法研究镀膜不锈钢试样在模拟纯对苯二甲酸(PTA)冲刷腐蚀环境中的耐冲刷腐蚀性能.结果表明:在静止环境中,Pd-Cu及Pd-Co膜层试样都表现出良好的耐蚀性,且Pd-Cu膜层试样的耐蚀性更优.但是,随着搅拌速度的增大,Pd-Cu膜层试样的冲刷腐蚀速率大大增加,而Pd-Co膜层试样的冲刷腐蚀速率仅有微小增加.与Pd-Cu镀层相比,Pd-Co镀层在所研究介质中的耐腐蚀性大致相当,但具有更高的硬度和更小的表面粗糙度,从而在具有冲刷环境的强还原性酸性介质中显示出优异的抗冲刷腐蚀性能.
