E - paint started to deposit on AZ31 Mg alloy after an inductance time and pores were found in the E - paint layer which is ascribed to hydrogen bubbles generated on the surface during the painting process . The pores disappeared after curing for 15 min at 160 o C . The E - paint on AZ31 exhibited good adhesion after immersion in deionized water for 500 h at 40 o C . The E - paint sample without scratch showed no corrosion after 1500 h of salt spray test . However , on the scratched sample , blisters were visible adjacent to the scratched sites after 500 h of salt spray test .
