Embodiment 1
[0015] This embodiment is an alloying method of a corrosion-resistant Mg-Ni-based high-damping alloy. Based on the Mg-Ni high-damping alloy, 3wt.% Ni and 1wt.% Mn are added, and Ni and Mn are respectively Mg-30wt .%Ni and Mg-5.5wt.%Mn are added in the form of master alloy, and Mg is industrial pure magnesium.
[0016] The preparation method of this embodiment is:
[0017] The first step is to preheat the crucible to 250°C, and paint the crucible coating for general magnesium alloy melting;
[0018] In the second step, the crucible is heated to 300°C, industrial pure Mg is added to the crucible and CO 2 +0.5vol%SF 6 Mixed gas for protection;
[0019] In the third step, continue to heat up until magnesium is completely melted, then add Mg-Ni and Mg-Mn master alloys at 710°C;
[0020] The fourth step is to continue to heat up to 730 ° C, keep warm and stir to fully melt the master alloy;
[0021] The fifth step, use C 2 Cl 6 Carry out refining treatment, and then pass thro...
