| 摘要 | PURPOSE: To obtain the subject member firmly covered with a solid lubricant without applying a binder to the sliding surface thereof by covering the sliding surface of a substrate comprising the ceramic sintered products of a Si compound with the compound of a IIa group element with Si and O in the substrate. CONSTITUTION: For example, CaF 2 powder 4 is placed on the sliding surface of a disk substrate 1 comprising a Si 3 N 4 sintered product and a lid 5 is downwardly moved to prevent the scatter of the powder 4. A heating oven 7 is heated with a heater 8 to heat and hold the lid 1 and the powder 4. A pressure is applied to the sliding surface of the disk substrate 1 with a pressing mechanism 6 and the substrate 1 is simultaneously rotated with a rotation mechanism 3, followed by stopping the rotation, removing the pressure from the sliding surface and cooling, thereby permitting to increase a contacting area between the substrate 1 and the powder 4 and accelerate a thermochemical reaction therebetween. The surface of the substrate 1 has microscopically many projections and depressions due to the failing, etc., of ceramic particles constituting the sintered product, but the powder 4 intrudes into the depressions to increase the adhesivity of the covering layer to the substrate 1. The sliding member has excellent sliding characteristics because of containing the CaF 2 in the sliding surface in a high ratio. COPYRIGHT: (C)1991,JPO&Japio |
