及び潤滑性が付与される。As mentioned above, in this invention, composite plating is applied to the surface of a sintered metal formed into a predetermined shape, and together with the plated metal, fine particles of a ceramic material having wear resistance and lubricity are used. It causes co-refraction of fine particles of ceramic material. Therefore, a plated metal film is formed on the surface of the bearing, including the bearing surface, and the film is coated with fine particles of wear-resistant ceramic material and fine particles of ceramic material with lubricity. As a result, wear resistance and lubricity are imparted to the bearing surface of the bearing or the sliding surface of the sliding metal member.

In other words, composite plating, also called dispersion plating, involves adding insoluble fine particles to a normal electroplating solution or chemical plating solution, dispersing them uniformly, and causing the fine particles to co-recipitate with the metal matrix on the surface of the object to be plated. While the dispersed fine particles are adsorbed on the surface of the object to be plated, they are embedded in the plating film one after another by the precipitated metal, and are co-fractionated to form a uniform split phase in the metal matrix. be.

すればよい。Therefore, in the present invention, fine particles of a ceramic material having lubricating properties and a ceramic material having wear resistance coexist on the surface of the bearing including the bearing surface (plated metal), and a film containing these is formed. will be done. Here, the reason why ceramic materials are used for the fine particles used in composite plating is that these ceramic materials have excellent hardness and thermal properties.There are also two types of ceramic materials: ceramic materials with good lubricity and ceramic materials with wear resistance. The relationship between the composition of the ceramic material in the above should be adjusted as appropriate depending on the purpose.For example, in a case where a high load For bearings that rotate at very high speeds, the proportion of wear-resistant ceramic material fine particles may be reduced, and then for high-speed rotation and low-speed rotation, the proportion may be increased.
なお、メッキ皮膜の厚みは、後に含油させることから、

Therefore, if the container is placed in a completely sealed container made of sintered metal with composite plating on its surface and the pressure inside the container is reduced, the pressure in the pores 2 in the sintered metal will also be reduced, and the lubricating oil will be absorbed into the pinholes 4. It passes all the way through and enters into the cavity 2. 3a is plated metal 3b
3C is a fine particle of a ceramic material having lubricating properties, and 3C is a fine particle of a ceramic material having wear resistance.
