摘要

The present study investigated the effects of friction stir processing in the water environment on the microstructure and corrosion characteristics of the Mg-1Er-1Pr alloy. This study introduces a novel technique by forming fine-grained microstructures to enhance the corrosion resistance and anodic performance of the friction stir-processed Mg-1Er-1Pr alloys in an aqueous environment. The UW-FSP was performed to reduce the grain size from ~ 243 to ~ 8.11 µm. The detailed characterization of phase evolution, microhardness, corrosion susceptibility, and corrosion kinetics was studied. The average microhardness of the stir zone increased approximately 60 HV compared to the base. The results demonstrated a decrease in anodic performance and an increase in anodic consumption rate compared to the base alloy. The anodic efficiency for the specimen UW-FSP was determined to be below 20%, indicating insufficient control of the anodic reaction.
