摘要：

The corrosion rate in a modified Hanks' solution (containing no Ca(2+)ions) was higher than in Hanks' solution. The increase was by a factor of similar to 12 for HP Mg and AZ91, and a factor of similar to 6 for WE43. This quantitatively highlights the critical role of Ca(2+)ions for Mg corrosion in synthetic body fluids. The Ca(2+)ion containing solutions produced a dense corrosion-product layer of hydroxyapatite, Ca-3(PO4)(2)) Ca(OH)(2), a greater fraction of which stayed on the corroding surface (similar to 0.2-0.3) compared with the Ca(2+)ion free solutions which produced magnesium phosphate, Mg-3(PO4)(2).
