解釋
加壓燒結-
In this paper, the alumina ceramic was prepared under normal pressure and low temperature, the mechanical properties, micromorphology, microstructure of grain boundary and phase composition of the alumina ceramic, and the precision shaping and cold processing of the femoral head were systematically studied ; the effects of the additives, the relation between microstructure and mechanical strength, the sintering mechanism of the material and the influence factors of the structure and properties of the alumina ceramic were discussed also
本文在常壓低溫條件下制備了氧化鋁陶瓷，系統研究了氧化鋁陶瓷材料的力學性能、微觀形貌、晶界顯微結構、相組成和股骨頭的精密成型、冷加工，並討論了添加劑的作用、材料顯微結構與力學強度的關系、材料的燒結機理及影響氧化鋁材料結構與性能的因素。 -
To micrometer sic powder, pressed compacts were made under 750 mpa pressure with sintering time ranging from 4 to 7h and sintering temperature ranging from 1600 to 1800 @, but to nanometer sic powder, pressed compacts are made under1000 mpa pressure with sintering temperature being 1600 ? and sintering time ranging from 4 to 5h. howerver, all compacts were sintered under an ar protection of 1. 0 atm pressure
