Anti-Corrosion Properties of Al-Based Coating on Magnesium Alloy Fabricated by Supersonic Particles Deposition

Abstract:

In order to improve anti-corrosion property of magnesium alloy parts in equipment, Al-based alloy coating on ZM5 magnesium alloy was prepared by supersonic particles deposition (SPD). Mass gain after being corroded, surface morphology of samples corroded and corrosion products were investigated by salt-mist test, SEM observation and EDS analysis etc. The results indicated that the mass gain of Al-Si coating after being corroded decreased evidently compared with magnesium alloy substrate. Al-Si coatings with thickness above 0.5mm did not generate blisters after 500h salt-mist test, proving that the coating possessed excellent anti-corrosion property.
