Weight loss resulting from immersion in 3%NaCl solution buffered with Mg(OH)2 has been determined for Mg alloy splats containing different levels of alloying with Zn or Al with and without ternary additions of Mn, Ce, Nd, and Si. The results show that additions of Zn increase the rate of dissolution, whereas an addition of 15 wt-%Al significantly reduces the dissolution rate. Ternary additions of Mn significantly reduce the dissolution rate of both Mg–Zn and Mg–Al alloys, whereas Ce and Nd reduce the dissolution rate of Mg–Al alloys. Additions of Si to Mg–Zn slightly increase the dissolution rate. These results are discussed in the context of other reported observations on the corrosion behaviour of rapidly solidified Mg alloys.
