    摘要: A metallic composite material according to the present invention is a metallic composite material, which comprises: a composited portion having a sintered body 1 being completed by sintering a metallic powder of a first metal, and a second metal 2' infiltrating into the pores of the superficial-layer portion of the sintered body 1 at least; and a parent-material portion having the second metal 2 covering the composited potion, and is characterized in that the sintered body 1 is completed by sintering the metallic powder together with a melt-disappearing material, which possesses a melting point being the sintering temperature of the metallic powder or less, or a burn-disappearing material, which burns to disappear at the sintering temperature or less; and the metallic composite material is equipped with a fitting portion at the interface between the composited portion and the parent-material portion, fitting portion which is formed by infiltrating the second metal 2' into the pores and additionally getting the second metal 2' into parts 3 where the melt-disappearing material has been melted to disappear or the burn-disappearing material has been burned to disappear. By means of this novel construction, it is possible to suppress the occurrence of cracks and peeling, which occurs in metallic composite material.
    In the present invention, the melt-disappearing material can preferably include an alloying component element, which forms an alloy with a major component element of the metallic powder. When major component element is iron and the alloying component element is copper, the strength of the fitting portion improves.

    摘要: A method for joining a metal foam to a metal part comprises the following steps:

    providing a metal part (14);
    providing an open cell metal foam (10);
    applying the metal foam (10) onto a surface (12) of the metal part (14);
    depositing e.g. by thermal decomposition of nickel carbonyl a metal onto the metal foam (10) and the surface (12) of the metal part (14) through the metal foam (10) in a quantity sufficient to join the metal foam to the metal part.
