Abstract

A new technique of surface modification by diffusion coating for AZ91D alloy was developed. A 1.0–2.0-mm alloy layer, which has hardness four to five times higher than the substrate metal, was formed after the treatment. Consequent solution treatment and aging could further improve the hardness of the alloy layer. Microstructure and chemical composition were investigated using optical microscope and electron probe.
