GK型人工机械瓣膜系国家科委攻关局主持,由航空航天部北京材料工艺研究所和中国医学科学院阜外医院共同承担的“六五”国家重点攻关项目。该项目采用钩孔单斜碟结构。瓣碟为石墨材料。采用热解沉积工艺获得耐磨性能良好的碳一碳涂层,瓣架为钴基生物合金,生 GK-type artificial mechanical valve is under the leadership of the State Science and Technology Commission’s Research and Service Bureau, and the “6th Five-Year” national key research project jointly undertaken by the Beijing Institute of Materials Technology and the Fuwai Hospital of Chinese Academy of Medical Sciences. The project uses a hook hole mono-slanted dish structure. The disc is graphite material. A pyrolytic deposition process is used to obtain a carbon-carbon coating with good wear resistance. The petal frame is a cobalt-based bioalloy.
