The corrosion resistance was greatly improved after HRDSR. This result was attributed to the enhanced stability of the Mg(OH)(2) layer due to the grain refinement and precipitation of various types of P-containing compounds on the stabilised Mg(OH)(2) layer. The HRDSR technique has a good potential to be used for the development of magnesium sheets with good combination of mechanical and biocorrosion properties. (C) 2013 Elsevier Ltd.
