| Popis: | Effects of pulsed magnetic field (PMF) on microstructure, mechanical properties and bio-corrosion behavior of Mg-7Zn alloy were investigated. Results show that the solidification microstructure of Mg-7Zn alloy was further refined with increasing discharging voltage. The second phase was changed from discontinuous reticular to island-like and particle-like morphology. Moreover, the volume fraction of second phase in the alloy treated by PMF was reduced. With PMF treatment, the mechanical properties of Mg-7Zn alloy were also enhanced. The PMF treatment was beneficial to the bio-corrosion resistance improvement of Mg-7Zn alloy. The corrosion rate of Mg-7Zn alloy was gradually decreased with increasing discharging voltage. |
