| 摘 要： | 将Ｆｅ－Ｗ非晶态镀层在铬酸盐钝化液中进行化学钝化与电化学钝化，使之形成含铬钝化膜。阳极极化曲线说明，钝化后镀层的孔蚀电位向正向移动了约１．６８Ｖ；Ｆｅ－Ｗ非晶镀层在氯化钠溶液中浸泡近１ｈ表面发生严重腐蚀，而经钝化处理的镀层浸泡１个月，表面无变化，仍具有金属光泽。

| Abstract: | The amorphous Fe-W deposit is passivated chemically and electrochemically inchromate solutions in order to form a passive film. Anodic polarization curves show that thepitting potential of passivation moves about 1.68V toward noble. Amorphous Fe-W depositswere corroded severelv within one hour in NaCl solution,but the passivated deposit exhibit-ed no change and maintained metal luster on the surface after one month of immersion. |
