Study on Modification of Novel Magnesium Alloy for Sports Equipment

The novel magnesium alloy for sports equipment is fabricated by adding alloy elements Mo and Y into AZ31 magnesium alloy and is subjected to variable-temperature homogenization treatment. Microstructure, phase composition, wear resistance and corrosion resistance of the novel magnesium alloy are tested and analysed. The result shows that due to the adding of the alloy elements Mo and Y and variable-temperature homogenization treatment, the microstructure of the magnesium alloy is refined significantly, and wear resistance and corrosion resistance of the alloy are improved. Compared with the AZ31 magnesium alloy, the novel magnesium alloy has the advantages that the wear volume is reduced by 59.21% and 67.92% before and after homogenization treatment respectively, and the positive displacement of corrosion potential is 84 mV and 95 mV before and after homogenization treatment respectively.
