The purpose of the present invention is to provide a novel cermet composite material having an antibacterial effect in which a ceramic phase containing silicon carbide and a metal phase containing Cu and Si are dispersed and mixed with each other. Disclosed is a cermet composite material containing a ceramic phase of silicon carbide and a metal phase containing an alloy of Cu and Si and/or an intermetallic compound in a mutually dispersed state, the metal phase containing at least one metal additive element M other than Cu or Si, the silicon carbide occupying more than half of the total mass of the constituent materials of the ceramic phase, when an image having an area of 256 [mu] m * 192 [mu] m is acquired at 500 magnification using a scanning electron microscope (SEM), the area ratio A/B of the ceramic phase/metal phase is 2-60, and when a is the mass fraction (%) of Si in the metal phase and m is the mass fraction (%) of the added element M, the relational expressions 0.01 < = m/a < = 1.4 and 0.3 < = m < = 20 are satisfied.
本公开的目的在于提供包含碳化硅的陶瓷相以及包含Cu及Si的金属相相互分散、混杂,具有抗菌效果的新型金属陶瓷复合材料。公开了一种金属陶瓷复合材料,其以相互分散的状态含有碳化硅的陶瓷相、包含Cu及Si的合金和/或金属间化合物的金属相,金属相含有Cu或Si之外的至少1种金属添加元素M,碳化硅占据陶瓷相的构成材料的总质量的过半量,使用扫描电子显微镜(SEM)以500倍率取得面积256μm×192μm的图像时,陶瓷相/金属相的面积比A/B为2以上且60以下,将金属相中Si的质量百分率(%)设为a、添加元素M的质量百分率(%)设为m时,满足关系式:0.01≤m/a≤1.4及0.3≤m≤20。
