Effects of Cold-Spray Coatings on the Corrosion Properties of AZ80 Magnesium Alloy

Article Preview

Abstract:

In this study, the coating layers of IN625 and 301 stainless steel powders were deposited on the AZ80 magnesium alloy substrates by cold-spray technique. The crystal structures, cross-section of the coating layers and anti-corrosion capabilities were examined via XRD, SEM, potentio-dynamic polarization and salt spray test. Experimental results show that the coating layers have a few porosities. The AZ80 substratesexhibit a phenomenon of grain refining after the cold-spraying. Meanwhile, these coating layers could improve significantly the alloy’s corrosion resistance.
