New aviationfriction materialThe development of friction materials and friction and wear mechanism is one of the important research directions of the laboratory. According to the needs of discipline development, national economy and national defense construction, the laboratory has developed research on aviation friction materials and friction and wear mechanism, and its research results have been successfully applied to the development of aviation brake materials.The Soviet made aircraft metal base brake pair developed in the laboratory has obtained the production license issued by Russia and passed the loading test, which is equivalent to adding a new type of aircraft. The above scientific research achievements have won the third prize of the National Science and Technology Progress Award;The laboratory has developed a type of imported aircraft brake pair, took the lead in completing the localization of the aircraft parts, and has its own intellectual property rights, making important contributions to national major projects. This scientific research achievement has won the second prize of the national invention award.On the basis of the above basic research, the laboratoryC/C compositeA series of basic and applied basic research, successfully developedBoeing 757aircraftC/C compositeThe brake pair has successfully passed various tests such as ground inertial platform test and installation flight test, and has entered into leading use, making China the fourth country in the world to master the manufacturing technology of C/C composite brake pairs after the United States, Britain and France.Various models of carbonbrake discSubstantive progress has been made in the development of, the brake disc has good braking performance, and the material performance has reached the internationally famous French SEP and BritishDunlopPerformance level of similar products of the company.
According to the characteristics of powder metallurgy technology and the international development trend in this field, the laboratory has selected powder injection molding, powderPlasticizingExtrusion andHot isostatic pressingThree current hottestpowder metallurgyNear net shape technologySystematic and in-depth research on powder rheology and plastic deformation related to the above technologies has been carried out, and a series of innovative achievements have been achieved.In this fieldNational Natural Science Foundation of ChinaKey project, "powder metallurgy"Near net shapeThe "Research on Rheology and Plastic Deformation in Full Densification Process" passed the national acceptance and was unanimously rated as "Grade A" by the review experts.During the implementation of the project, 83 academic papers were published in well-known journals at home and abroad, including《SCI》It included 15 articles, 35 of which were included in EI, and made four invited reports at international academic conferences.Published two monographs, Rheology of Powder Injection Molding and TiAl Intermetallic Compounds.In addition, the doctoral thesis of the laboratory "Research on the properties of paraffin based binder and oil-based binder for metal injection molding" won the National Excellent Doctoral Thesis Award.Its related achievements won 2 provincial and ministerial science and technology progress awards, and applied for 4 invention patents. Based on the above research achievements, 8 new products were developed.It has formed an internationally advanced metal powder rheological and plastic deformation technology with independent intellectual property rights, which is of great significance to the national economy and national defense modernization.
The laboratory has further strengthened its basic research work. In the past six years, the laboratory has undertaken national“nine hundred and seventy-three”5 items.Material design, phase diagram prediction as physical metallurgy, thermochemistry andComputer applicationIn recent years, it has developed very rapidly.The laboratory was first proposed and developed in the worldAlloying phaseIt has developed the diffusion couple technology and established a theoretical framework for simulating the evolution of materials under special conditions. This research achievement occupies an important academic position in the world.In addition, in the laboratory, TiAl high-temperature structural materials, high densityHeavy alloy、Special ceramics、Warm pressureForming technology, electrical materials, high-performance vehiclesfriction materialWe have made great achievements in the research and development ofPilot productionAnd industrialization provide the source of scientific and technological achievements and make important contributions to the national economy and national defense construction.
