| Abstract: |
| As high temperature self-lubricating coatings for modern high-tech equipment use are confronted with increasingly complex conditions, high service temperature, and more rigorous requirements for high reliability and long life, it is in urgent need to study environmental suitability and stability of novel high temperature self-adaptive lubricating coatings under service conditions. Component design and relevant preparation technology of the coatings at home and abroad were reviewed. Research status of high temperature self-lubricating coatings prepared by thermal spraying technology was analyzed emphatically. Achievements and shortcoming of the technology were elaborated from the aspect of preparation technology and component regulation. It was propose that advanced spraying equipment and spraying powders consisting of similar phase component should be used to prepare thermal sprayed high temperature self-lubricating coatings by referring to component design regulation. Besides, the regulation should guarantee superior mechanical properties, corrosion resistance and high temperature oxidation resistance so that the coating could exhibit excellent high temperature self-lubricant property by virtue of tribological physical or chemical process at high temperature. Coating structure-activity relationship and comprehensive application property were studied emphatically. Furthermore, material oxidation thermodynamics-kinetic theory was employed to evaluate comprehensive use performance of materials and discuss high-temperature lubricating friction mechanism from the aspects of “high-temperature mechanics-high-temperature tribology-high temperature resistance stability”. |
