Development of physical vapour deposited Mg–Zr alloys Part 3 – Comparison of alloying and corrosion behaviour in Mg–V and Mg–Zr physical vapour deposited alloys
The microstructures and corrosion products of Mg–V and Mg–Zr physical vapour deposited alloys were compared. Factors affecting the alloying behaviour of Mg with V or Zr as well as with other alloying additions such as Ti, Cr, Mn, and Si were considered. The greater thermodynamic stability of the Zr oxide in air and Zr hydroxide in 3 wt-%NaCl were the main reasons for the enhanced corrosion resistance of Mg–Zr alloys compared to Mg–V alloys.
