  • Ceramic-sprayed member and process for making the same
    Patent number: 4885213
    Abstract: A sprayed member which has a ceramic-sprayed layer formed on the surface of a parent material of an aluminum alloy through a sprayed bond layer. A diffusion layer occupies 20 to 50% of the entire interface between the bond layer and the parent material. The interface between the diffusion layer and the parent material and the interface between the bond layer and the parent material are finely roughened to have a height of several microns. The diffusion layer and the fine roughness are formed by preheating the surface of the parent material at a temperature ranging from 260.degree. to 500.degree. C. prior to spraying the parent material with a material for the bond layer so that they can together enhance the adherency between the bond layer and the parent material.
