Abstract

Electrochemical tests and microhardness tests were carried out on Mg-Gd, Mg-Ca, Mg- Zn, Mg-Mn, Mg-Zr and Mg-Sr binary alloys and Mg-Mn-Zr, Mg-Ca-Zn ternary alloys in the 'as-cast' state. These are one subset of a group of alloys which represent the Al-free class of Magnesium alloys. It is shown that most elemental additions increase the corrosion rate of Magnesium due to enhanced cathodic reaction kinetics. However, there are some notable exceptions in that Zn and Mn in binary additions can moderate the corrosion rate of Magnesium. When present in ternary additions, the relationships between elemental additions, corrosion, and hardness, become more complex.
