Abstract

The invention discloses a processing method of a solid lubricating coating for a surface texture. By alternating deposition of a nanocrystalline coating and a lubricating texture coating, a multi-layer graphite coating structure is generated, the lubricating coating can be packaged by the multi-layer graphite coating structure through the nanocrystalline coating with good mechanical property and morphology, so that the service life and the bearing capacity of the coating are improved. Meanwhile, the number of layers of the multi-layer lubricating layer is designed corresponding to the number of layers of bearing friction, so that the lubricating layer is exposed out of a fresh-time layer material to correspond to new friction after being worn, the persistence of the friction reduction effect is ensured, the use effect and the service life of a friction reduction texture are prolonged, and excessive wear and failure of a friction reduction layer are avoided.

Description

technical field [0001] The invention specifically relates to a processing method for a surface textured solid lubricating coating. Background technique [0002] Sliding friction pair parts such as bearing bushes and guide rails for machine tools, due to the large impact and vibration loads in use, long contact working time, and extreme high temperature and high pressure environment, will cause abrasion damage after a period of operation, precision and safety reliability drop to failure. Traditional lubricating oils and greases are difficult to meet the requirements of special working conditions due to their shortcomings such as large environmental pollution, volatile, and inability to use in vacuum environments. Therefore, the development of solid lubricating coatings is of great significance, and the low-cost The preparation of high-performance repairing and strengthening coatings with anti-friction properties will help reduce the operating energy consumption caused by fri...
