Abstract
A metallic mold-casting method excellent in the resistance to penetration is herein disclosed and the method comprises the steps of forming a coating layer by applying a mixture comprising at least one member selected from the group consisting of high melting metals, ceramic materials and graphite, and an aqueous surfactant solution or low boiling liquid oils and fats to at least part of the surface of a metallic mold on its cavity side, then applying heat to the coated portion to thus adhere the mixture to the inner surface of the mold, and thereafter repeatedly casting a magnesium alloy in the metallic mold provided with the coating layer. The metallic mold-casting method permits the metallic mold casting of magnesium alloys with good resistance to penetration and this accordingly leads to the production of a cheap and high quality cast magnesium alloy product.
