Study on Corrosion Properties of Medical Mg-Zn Alloy

Casting Mg-Zn alloy was corroded on the surface and analyzed the corrosion morphology and corrosion properties under different corrosion conditions. The results show that Mg-Zn alloy is unevenly by corrosion in simulated body fluids and the corrosion products are brittle and easy to break. With the increase of Zn content in Mg-Zn alloy, the corrosion rate of casting Mg-Zn alloy in simulated body fluid is improved obviously.
