| Abstract: | AZ91D magnesium alloy was selected as the matrix metal.SEM,EDS,spot test,Tafel and EIS were adopted to investigate the influence of concentration of phytic acid on appearance,component and corrosion resistance of conversion coatings.Results showed that the phytic acid conversion coating mainly contains Mg,Al,O,P and C.The content of Mg increases as the concentration of phytic acid increases,while the content of P is the other.The cracks in conversion coating have barely influence on its corrosion resistance... |
