What is the working principle of auto metal wear self-repair technology?

The self-repairing technology of metal wear is an advanced technology in the world, which produces the self-repairing effect of metal through the scientific application of physical chemistry and friction heat generation. Its essence is to use the repair material composed of additives, catalysts and mineral powder, and effectively put it into grease, which can form a good wear-resistant protective layer of cermet.

The protective layer can automatically compensate the friction and wear area of mechanical parts, realize the automatic recovery of mechanical parts wear and prolong the service life of parts. The most remarkable feature of metal wear self-repairing technology is universality, which is widely used in the field of machinery industry, helping China to comprehensively enhance the competitiveness of industrial products and promote the stable and sustainable development of China's industrial economic construction.

Generally speaking, the working principle of metal wear self-repair technology is to effectively form a strong protective layer on the friction and wear surface of mechanical parts by using catalysts and additives based on grinding and replacement reactions. The application advantage of this protective layer lies in its good corrosion resistance, super-lubricity and high hardness, which can help people reduce the serious wear of mechanical parts caused by high-intensity motion friction and save more unnecessary energy consumption.

In automobile maintenance, automobile maintenance personnel will use high-quality self-repairing materials when using metal wear self-repairing technology. The fine particles in this material will effectively penetrate into the mechanical parts of the friction automobile engine based on the lubricating carrier, and play its ultra-fine grinding role in the running friction process of the mechanical parts, and then the microstructure of the metal surface of the mechanical parts will gradually change under the physical and chemical reaction.

Under the auxiliary friction of the metal wear self-repairing material, the tiny particles in the metal wear self-repairing material will break and smooth the micro-convex part of the worn metal surface, thus smoothly improving the surface smoothness of mechanical parts.

In the process of friction between metal wear self-repairing materials and mechanical parts, the worn parts of the parts will flash when they break, which will promote the substitution reaction between magnesium atoms in the microcrystals of metal wear self-repairing materials and iron atoms contained in the mechanical parts, and lead to metallurgical and sintering changes under the action of additives and catalysts, and finally automatically form an iron-based silicate protective layer on the surface of mechanical parts.

The most remarkable feature of iron-based silicate protective layer is selectivity, and its forming conditions often exist only on the friction surface of mechanical parts. In the automobile structure, those parts that do not rotate by friction will not generate friction heat energy, so there will be no replacement reaction. Only those mechanical parts that rotate during operation will react with metal wear self-repairing materials to form corresponding protective layers, so as to realize automatic repair and protection of friction and wear parts of parts.
