He presided over a number of National Natural Science Foundation projects: carried out research on "mechanical behavior and characteristic evaluation of membrane/matrix composite systems" and "tribological characteristics and evaluation methods of heterogeneous materials and surface layers", and developed new The pendulum impact scratch testing machine and corresponding test methods and evaluation criteria were identified by the Shenyang Branch of the Chinese Academy of Sciences as "the first time to propose energy criteria for film/base bonding strength", and the results obtained the national invention patent; "room temperature-high temperature mixed lubrication mode and new "Exploration of Compatibility of Friction-Reducing Additives", based on the background of high-temperature and low-heat-loss engines, the compatibility of metal thiomolybdate nanopowder and lubricant was developed, which showed good friction-reducing performance at both normal and high temperatures, and established a new model for reducing friction from fluid to solid. Hybrid lubrication mode with smooth transition of friction; the "Metal Film Dynamic Mechanical Performance Evaluation and Energy Criteria" project further develops testing methods, in-depth explores the mechanism of impact scratches from both experimental and theoretical aspects, and uses tribological criteria as a dynamic Characterization of mechanical properties; research on "tribological behavior criteria in the application of material surface technology", conducting in-depth work on tribological experiments of various types of coatings and material-modified surface layers, material properties and friction and wear laws, contact stress calculation models, etc. .
Undertake the task of developing special thermal control facilities, and study the usage rules of materials in special environments and the materials, processes and engineering applications of thermal control devices. The project passed the expert appraisal of scientific and technological achievements of the Chinese Academy of Sciences and was evaluated as "reaching the advanced level of similar foreign technologies", and the results have won a number of high-level awards. With the support of the 863 New Concept Materials Project and the Innovation Fund of the Academy of Sciences, basic research work on key materials for thermal control was carried out. Three-dimensional reticular foam electrothermal alloys were prepared using methods such as electrodeposition and solid phase infiltration, and their structural composition, electrical and mechanical properties were studied. And the compatibility under the decomposition atmosphere of hydrazine, the project passed the acceptance of the project expert group
