Explain the law. After processing a base material such as steel, stainless steel, copper alloy, aluminum alloy, resin, etc. into a sliding bearing lining, it was degreased in an alkaline treatment liquid such as caustic soda, and then washed with water and hot water to adhere to the surface. Remove the alkali. For example, when it is necessary to increase the adhesion of the solid lubricating film, the surface of the lining is roughened by a chemical treatment such as a combination of alkali etching and pickling after degreasing, and the lining is mechanically treated by shot blasting or the like. Methods such as roughening the surface and forming irregularities on the lining surface by boring or the like can be used. When it is necessary to further increase the adhesion, the surface of the lining may be subjected to a chemical conversion treatment of zinc phosphate or zinc calcium phosphate having a thickness of 0.1 to 5 μm. When a base treatment such as boring is combined with a chemical conversion treatment, a lubricating film layer having extremely high adhesion can be obtained.

In addition to the spray method, the solid lubricating film can be formed by a method such as a tumbling method, a dipping method, a brushing method, and a printing method. The thickness of the lubricating film is preferably 1 to 50 μm.
