Abstract:
A metal-ceramic composite includes a ceramic substrate and a metallic composite. A groove is formed in a surface of the ceramic substrate and the metallic composite is filled in the groove. The metallic composite includes a Zr based alloy-A composite. A includes at least one selected from a group consisting of W, Mo, Ni, Cr, stainless steel, WC, TiC, SiC, ZrC and ZrO 2 . Based on the total volume of the Zr based alloy-A composite, the content of A is about30%to about70%by volume.A method for preparing the metal-ceramic composite is also provided.
