Abstract
The pseudo Zn-Al alloy coating was prepared by means of arc spraying.The electrochemical corrosion properties of pseudo Zn-Al alloy coating were investigated by using the measurement data of corrosion potential,polarization resistance and neutral salt-spraying test.The testing results showed that the pseudo Zn-Al alloy coating has better cathodic protection and corrosion resistance than the Zn-Al alloy coating.
