Study of Arc Spraying Technology and Corrosion Resistance of AZ91D Alloy Surface with Al-based Coating

XU Dao-rong

Abstract

The Al-based coating on AZ91D alloy surface was prepared by arc spraying technology.The effect of arc spraying process parameters on the quality of the coating was investigated,and the corrosion resistance experiments of AZ91D alloy with Al-based coating was carried out.The results show that an uniformity and dense Al-based coating can be obtained on AZ91D alloy surface.The corrosion resistance of the AZ91D alloy with Al-based coating is improved significantly by arc spraying.
