CORROSION RESISTANCE OF A CONVERSION FILM FORMED ON ALUMINIUM BY TETRAVALENT CERIUM SALT
铝合金表面四价铈盐转化膜及其耐蚀性

A new technology of SRE for forming conversion film on aluminium from tetravalent cerium salt was develeped. The effect of process factors on the corrosion resistance and the film forming kinetics was investigated. After SRE treatment, the corrosion resistance of aluminium alloy in chloride containing solutions was noticeably improved.
