摘要： A process for producing a ceramic body suitable for surgical implantation that has high strength and toughness and good compatibility with bone material. A porous material is provided by semi-sintering a ceramic compact. The pores in the surface of the porous material are filled with a first powder of either tricalcium phosphate or apatite or both, or with a material of the fine powder and a powder of a material substantially the same as the material of the ceramic compact. The porous material is then fired at the sintering temperature of the ceramic compact. Following sintering, the surface of the porous material is coated with a fine apatite powder or a finally pulverized mixture of apatite and a calcium phosphate base frit. The resulting assembly is then fired at a temperature up to about 1,350.degree. C.

摘要： Ceramic-based substrate for coating, e.g., diamond has a basic irregularities surface having a surface roughness Rz of 2 to 20 .mu.m, with Rz at angle regions of 40% or more of that for other than the angle regions. The basic irregularities surface has micro-sized irregularities on an order of crystal grains constituting the uppermost surface (0.5 to 10 .mu.m), forming dual irregularities surface structure. Coating layer engages with surface irregularities to secure firm adhesion at the cutting edge. WC-based cemented carbide is used as substrate and N-containing surface layer is formed by heat treatment to form the surface irregularities.

摘要： Diamond coating member is produced by a method comprising a first coating step in which the first diamond coating layer is closely formed on fine irregularity parts of a substrate having fine irregularities substantially without void left between them and the fine irregularities is engaged with the above first layer to coat the above substrate, and a second coating step in which the surface of the first coating layer is coated with a second diamond coating layer comprising diamond having a higher wear resistance than that of the first coating layer. The diamond coating member is excellent in adhesion between the diamond coating layer and the substrate and has high durability without having the diamond coating layer scaled off by mechanical shocks.
