研究了具有fcc晶相、非晶相和bcc晶相结构的Al 100-xMox合金（x = 10，26，50）薄膜在3.5%NaCl溶液中的腐蚀行为。Al 100-xMox合金膜的腐蚀行为受成分和相结构的协同作用控制，而不仅仅受Mo含量的影响。与固溶晶相的Al 90 Mo 10和Al 50 Mo 50薄膜相比，非晶相的Al 74 Mo 26薄膜钝化膜稳定，相结构均匀，Mo含量合适，具有上级的耐蚀性。系统阐述了不同相结构的Al 100-xMox合金膜的腐蚀机理。
The corrosion behavior of Al100-xMoxalloy (x = 10, 26, 50) films possessed fcc crystalline, amorphous and bcc crystalline phase structure were investigated in 3.5% NaCl solution. The corrosion behavior of Al100-xMoxalloy films were controlled by the synergy of composition and phase structure rather than affected merely by the Mo content. The Al74Mo26film with amorphous phase, compared with Al90Mo10and Al50Mo50films with solid-solution crystalline phase, displayed the superior corrosion resistance due to its stable passive film, homogeneous phase structure and proper Mo content. The corrosion mechanisms of Al100-xMoxalloy films with different phase structures were illuminated systematically.
