Abstract

The functional polymeric thin-film was prepared on the surface of AZ31 magnesium alloy by polymeric plating.The growth mechanism of polymeric film was investigated through analyzing cyclic voltammetry curves during polymeric plating.The results indicate that formation process of polymeric film on magnesium alloy surface undergoes three stages of nucleation

stable growth

and film thickening.Combined with salt spraying corrosion testing

the corrosion behavior of magnesium alloy surface was analyzed

and the optimized processing parameters were presented.
