| Abstract: |
| The wear of moving parts is increased when the lubricating grease fails or there is no lubricating medium. The preparation of self-lubricating composite coatings on the surface of the parts by laser technology is one of the effective solutions. This paper introduces the quality evaluation indicators of self-lubricating composite coatings prepared by laser technology, and classifies the matrix materials of self-lubricating composite coatings in detail, from metal-based, ceramic-based, and polymer-based self-lubricating composite coatings. The existing problems of self-lubricating composite coatings are pointed out based on previous theoretical research and practical application. The improvement of wear and friction reduction performance of self-lubricating composite coatings is obvious, and the research methods and progress of different coating materials are different. The research progress in this field is summarized, and the future research direction of self-lubricating composite coatings prepared by laser is prospected. |
