Description
上述した課題を解決し、目的を達成するために、本開示に係る封孔処理された金属複合体は、鉄系の金属材料からなる多孔質体の空孔部に銅または銅合金が充填された溶浸体と、溶浸体の表面の少なくとも一部に配置され、酸化されたクロムを有する酸化層と、を備える。溶浸体は、酸化層との界面に、鉄系の金属材料の密度が多孔質体の酸化層と接する部分以外の密度よりも高い緻密化層を有する。 In order to solve the above-mentioned problems and achieve the objectives, a sealed metal composite according to the present disclosure is provided in which the pores of a porous body made of an iron-based metal material are filled with copper or a copper alloy. an oxidized layer having oxidized chromium and disposed on at least a portion of the surface of the infiltrated body. The infiltrated body has a densified layer at the interface with the oxidized layer, in which the density of the iron-based metal material is higher than the density of the porous body other than the portion in contact with the oxidized layer .
