Rare-earth ZE41 alloy possesses unique mechanical properties. However, the sharp potential difference between the rare-earth phases (cathode) inside the Mg matrix (anode) results in building up micro-electrochemic al cells and enhancing galvanic corrosion. The optimum conditions for obtaining protective tungstate coatings having improved corrosion resistance for ZE41 alloy were determined. A simple one step surface treatment in 4 g/l tungstate coating solution for short time was found promising to improve the localized corrosion resistance.
