摘　　要：提出了一种铝合金铈盐化学转化成膜工艺。利用电化学方法研究了铝合金铈盐化学转化膜的成膜过程及耐蚀性能。结果表明 :成膜促进剂的加入能有效提高铈盐转化膜的成膜速度 。A process of forming chemical conversion coatings on LY12 hard aluminum alloy in cerium salt solutions was advanced. Formation and corrosion resistance of the chemical conversion coatings were studied by electrochemical methods. Results show that accelerant A can raise the speed of the conversion coatings greatly. and the formed coatings have good restrain action on pitting of aluminum alloy.
