| Abstract: | Effects of RE,Sb and Si additions on corrosion rate of AZ91D-based alloys were studied in NaCl solution with reference to weight loss. The microstructure of AZ91D magnesium alloy changes with the variation of additional quantity of the elements, which result in corrosion rate presenting different changing tendencies. Corrosion resistance increased because of addition of RE to the AZ91D alloy, and decreased according to additions of Si and Sb within certain range (less than 1.5%). |
