摘要： A diamond-coated body is prepared by coating a diamond film on the surface of a sintered body by means of vapor phase synthesis, the sintered body being so prepared by subjecting a sintered body prepared from ceramics based on silicon nitride to heat treatment at the temperature of 1,400.degree. C. to 1,700.degree. C. as to give a crystalline intergranular phase. The resulting diamond-coated body has excellent adhesion between the diamond film and the substrate and it is appropriately employed for cutting tools and so on because, when applied to the cutting tools, they can be used for cutting for a long period of time.

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： 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.
