Characteristic Features of the Preparation of Porous Magnesium Castings via Melt Infiltration through Water-Soluble Salts

Owing to its low density and good damping properties, magnesium is a promising material for industrial and medical applications. We propose a process for the fabrication of porous magnesium products via melt infiltration through water-soluble granules prepared from sodium chloride-, sodium carbonate-, and sodium hydrogen carbonate-based salts. The effect of granule composition on the corrosion resistance of porous magnesium during leaching has been studied, the granule composition has been optimized, and processes for the fabrication of granules and porous magnesium products have been proposed.
