Self-lubricating technology - making life better

Self-lubricating materials (also known as solid self-lubricating materials) refer to materials that use solid powders, films or some overall materials to reduce friction and wear between two load-bearing surfaces. During the solid lubrication process, the solid lubricating material and the surrounding medium undergo physical and chemical reactions with the friction surface to form a solid lubricating film to reduce friction and wear. The technology that uses solid lubricating materials to lubricate the friction cross section is called self-lubricating technology.Self-lubricating technology can be used in many aspects, such as self-lubricating bearings.
Commonly used self-lubricating materials
Self-lubricating composite materials are composite materials with certain strength and self-lubricating properties prepared through a certain process, using metal, ceramic or non-metal as the basic components, adding solid lubricants and some additional components. It has both the mechanical properties of the matrix component and the tribological properties of the solid lubricant. It has excellent comprehensive performance and is suitable for special working conditions such as various atmospheric environments, chemical environments, electrical environments, high temperatures, low temperatures, high vacuum, strong radiation, etc. Next work. Mainly divided into metal-based lubricating materials, polymer-based self-lubricating materials, and inorganic non-metal-based self-lubricating materials. The solid lubricants currently commercialized mainly include: graphite, molybdenum disulfide, polytetrafluoroethylene, etc.

Application of self-lubricating technology
Solid lubricants are commonly used in mechanical processing, pressure processing, cutting processing and some special working conditions. Common applications in daily life include:
Self-lubricating tools: solid lubricants can be coated on the surface of the tool using methods such as coating, and a solid lubricant film can also be formed on the surface of the tool using surface treatment methods such as ion implantation, so that the tool has a self-lubricating function; solid lubricants can also be applied to the tool surface. Lubricant is added as an additive to the tool material matrix, taking advantage of the advantages of solid lubricants to form a continuous solid lubricating layer on the tool surface.
Self-lubricating bearings: mainly divided into inlaid type and powder metallurgy integral sintering molding. Inlaid type refers to pre-designing and processing certain holes or grooves on the metal substrate, and embedding solid lubricating materials in them, so that the two are combined into a whole and used as bearings, bearing bushes or linings; powder metallurgy integral sintering self-lubricating Bearing refers to adding solid lubricant in the form of powder to the metal matrix raw material, and forming a self-lubricating composite material through compression molding and sintering, which is used as a bearing, bearing bush or lining plate.

Self-lubricating grinding wheel (impregnated grinding wheel): During the grinding process of the impregnated grinding wheel, the impregnating agent in the grinding wheel is easily melted under the action of high temperature and can be directly applied to the grinding area. The impregnating agent is actually made of a variety of Cutting aids composed of additives that improve cutting performance.
