摘要
探索月球、火星及其他行星时,采用软金属铟银合金进行高真空密封成为采样密封的最佳选择。高真空密封技术的工艺具有易实现、高适应、高密封的特点。通过工艺试验解决密封材料的成分比例、刀口的构型和加工精度、刀口的刃入深度等关键技术,达到了航天应用的技术要求,能够适应恶劣的高真空、高辐射、高低温等空间环境。
High vacuum sealing with soft metal marriage is adopted to provide the best choice to realize sampling seal when exploring the Luna,Mars and other plants.The process of high vacuum sealing technology has the advantages of easy realization,high adaptability and high sealing property.Through the process test for obtaining ingredient percentage of sealing material,confirming the configuration and the accuracy knife edge,acquiring depth of the knife edge entrance,etc..It has been solved by the technological test,which can meet the requirements of the spacecraft application,and it completely can adapt to the space environment of the atrocious high vacuum and high radiation,high and low temperature.
