Abstract

The invention provides an LIS coating and a preparation method and application thereof. The LIS coating comprises lubricating oil and a solid coating, the solid coating comprises a low-surface-energy layer and a composite bonding layer which are sequentially arranged in a stacked mode, and the lubricating oil is soaked in the low-surface-energy layer; and the low surface energy layer comprises GrF and PTFE (Polytetrafluoroethylene). The LIS coating provided by the invention is low in friction coefficient, good in chemical robustness and high in corrosion resistance, and shows huge application potential in the fields of tribology and metal corrosion protection.

Description

technical field [0001] The invention belongs to the field of lubricating materials, and in particular relates to a LIS coating and its preparation method and application, in particular to a low friction coefficient LIS coating and its preparation method and application. Background technique [0002] Reducing friction and wear is very necessary in production and life, because they usually lead to component failure, excessive energy consumption and greenhouse gas emissions, and even serious disasters. Therefore, reducing mechanical energy consumption and prolonging equipment life are important strategies. Liquid and grease-based lubricants are commonly used to reduce friction and wear in moving mechanical systems by creating a thin liquid film to isolate rubbing parts. Recent studies have found that some water and oil-based lubricants exhibit superlubricity. However, this superlubricated state usually involves frictional reactions and surface adsorption of exotic materials. ...
