[Abstract]:With the development of high and new technology equipment such as aerospace, it is very important to develop self-lubricating materials which can adapt to very high temperature because of the requirement of excellent tribological properties of related moving parts at very high temperature. The research and development of binary oxide lubricating materials and ternary oxide lubricating materials as high temperature solid lubricating materials are reviewed. The tribological properties of binary and ternary oxide lubricating materials containing Magn 茅 li homologous phase in high temperature and wide temperature range are introduced. The growth structure and defect form of the materials are also described. It has become a potential method to realize high temperature lubrication of materials. The dependence of the structure, chemical and electrical properties of these oxides on their tribological properties is also discussed. Finally, the prospect of the application of oxide lubricating materials in industry is summarized, and it is proposed that the development of single lubricating materials to realize continuous lubrication in the wide temperature range from room temperature to high temperature (251000 鈩，
