%X An optimal bath composition of phosphating for steel at ambient temperatures is obtained by orthogonal trial tests.Metallographic observation reveals that the phosphating coating is compact and continuous.The forming process of phosphating coatings was studied by electrochemical method.The dynamic polarization curves indicated that the corrosion-current keeps nearly not change after the coating formation.The chemical composition of the formed coating was investigated by X-ray photoelectron spectroscopy(XPS).It showed that phosphating coating may be made of phosphates of Fe and Zn because there are some obvious peaks of Zn,Fe,P elements and different spectrographic peak of O.At the same time,it was shown that this phosphating bath is stable,less sludge and higher film-formation rate.The phosphating coating formed with this bath has good corrosion-resistance.
