Abstract Phosphating primer and anoding chemical conversion film were measured using 3 measurement of salt spray corrosion tests,potentiosta tic anodic polarization curves and electrochemical impedance spectroscopy(EIS).I t were discovered from the result that corrosion-resistance of phosphating pri mer was still better by comparison with anoding chemical conversion film.Anoding chemical conversion film was markedly corroded but phosphating primer was as th e same as original state in 10 cycles of neutral salt spray corrosion tests.Corr osion-resistance of both was similar within the part of stable state and weak po caviztion,but corrosion-resistance of phosphating primer was obviously better th an anoding chemical conversion film within the part of strong polarization.Polar ization resistance (Rp) of phosphating primer was a order of magnitude hig her ghan anoding chemical conversion film on EIS.

Key words: anoding phosphating primer salt spray corrosion test EIS anodic polarization
