Document Type and Number:
Japanese Patent JP4291705
Kind Code:
B2
Abstract:
A method of molding a composite metal material capable of increasing the smoothness of the specified surface (composite surface) thereof joined to a porous preliminary molding. In the method of molding the composite metal material (3), a releasing material formed of a scale-shaped composition is applied to the molded surface (5) of the porous preliminary molding (1) and the porous preliminary molding (1) is heated to form a scale-shaped coating layer (6), the molded surface (5) is brought into contact with a molding die (22) forming the specified surface (or composite surface (4)) joined to the porous preliminary molding (1), and the molten metal (2a) of a light metal is supplied while pressurizing. Thus, the specified surface (or composite surface (4)) having approximately smooth casting surface can be formed, void is prevented from being formed in the material, and the light metal and the porous preliminary molding can sufficiently develop their excellent characteristics in the composite metal material (3).
