摘要： Disclosed is a process for preparation of a sintered silicon nitride. The process comprises the steps of:mixing a powder of silicon nitride with a powder of a sintering agent;compacting the obtained mixture; andsintering the compacted mixture in a non-oxidizing atmosphere.The feature of the process is that the powder of the sintering agent includes a powder mixture of oxide and/or hydroxide of at least two kinds of metals which has been prepared by co-precipitation.Due to the use of the co-precipitated powder as the sintering agent, it is possible to obtain a sintered silicon nitride having an excellent strength and uniformity in quality. The obtained sintered silicon nitride is preferably used as an engineering ceramic.

摘要： To provide sliding components each comprising a base metal and, joined thereto, a sliding face member having a sliding face of crowning profile, in particular, sliding components such as valve train parts, a cam follower and a rocker arm of an automobile engine. A sliding component having a structure comprising (1) a ceramic forming a sliding face and (2) a base metal joined together, in which the extent of crowning of the sliding face is at least 0.1 to 0.4% of the maximum length of the junction face of the ceramic. The ceramic has a four-point flexural strength of at least 50 Kg/mm as measured in accordance with the Japanese Industrial Standard R1601. The base metal is mainly steel at least the surface of which has preferably a martensite texture and has a hardness of higher than 45 in terms of H.sub.RC. The structure may have an intermediate layer of a metal or cermet. In one mode the junction of the sliding face member such as a ceramic of crowning profile is simultaneously carried out with the formation of the base metal part and in another mode the sliding face of the base metal is hardened by the heating after the junction. A sliding component whose extent of crowning is great can be provided at a lowered cost without suffering from defects such as cracking.

摘要： A combination of an adjusting shim and a cam used in a valve train in an internal combustion engine for automobiles, the adjusting shim composed of a ceramic material which sets the surface roughness of a sliding surface of the adjusting shim with respect to a cam to not more than 0.1 .mu.m in ten-point mean roughness Rz, and which contains not less than 60 vol. % of silicon nitride or sialon, and the cam composed of cast iron a surface of which is chill hardened and then provided with a phosphate film thereon. The combination of an adjusting shim and a cam is capable of smoothing a sliding surface of the cam by the break-in of the part even if the cam is not subjected to a super-precision finishing process; preventing the seizure and abnormal abrasion of sliding surfaces; stabilizing a smoothed condition of the sliding surfaces of the cam and shim for a long period of time; and providing excellent sliding characteristics of the sliding surfaces owing to a decrease in the friction coefficient thereof.
