Study on corrosion resistance of a rust-transforming treatment solution

A kind of rust-transforming treatment solution was developed based on oxime compound (coded as SO),and the corrosion resistance of the sample immersed in 3.5% (mass fraction) NaCl solution was studied by electrochemical impedance spectroscopy and surface observation. The results indicated that SO has a distinct rust transforming effect by forming a red-brown chelate compound film on the surface of iron and steel with rust. The SO combined with a suitable film forming resin has a obvious effect on improving corrosion resistance of rusted iron and steel.
