The Function and the Principle about How Self-healing Materials are Used in Metal Wear Condition

Due to the wide range of metals used in different industries, the increase in the service life of metals and metal materials has always been a more important research direction. Relevant research has proved that self-repairing materials in lubricants can help machines to repair themselves by utilizing self-modifying properties, thus restoring them to a better working condition. This paper mainly summarizes and analyzes the experimental materials by means of literature review, and discusses the working principle of such materials and the application of self-repairing materials in industrial production. The article also confirms through its analysis that during the operation of the machine, the composite lubricant reacts with the metal surface and forms a thin film, which results in a substitution reaction. In this way, the damaged metal is replenished by the composite material and the machine can return to normal operation. However, this method can only be applied to machines that work for a short period of time, and is not able to solve the problem of large areas of severely damaged machines, so the relevant materials to assist in the modification of the metal still need to be continuously developed and researched.
