    摘要:

    綜述了航天航空用難熔金屬鎢、鉬、鉭、鈮、錸和其合金及其涂層在高溫結(jié)構(gòu)研究方面的現(xiàn)狀和應(yīng)用情況，對航天用難熔金屬合金的種類、力學(xué)性能、涂層的性能、制備方法作了介紹。難熔金屬主要用于火箭發(fā)動機和航天器結(jié)構(gòu)件，其中鎢、鉬及其合金單晶應(yīng)用于空間動力系統(tǒng)。難熔金屬及其合金的使用溫度高低順序與材料熔點的順序相同。

    Abstract:

    The research states and applications of refractory metals tungsten, molybdenum, tantalum, niobium and rhenium and their alloys and coatings used in spaceflight industry, have been summarized. The kinds, mechanical properties and preparation technologies of the alloys and performances of their coatings have also been introduced. The refractory metals are mainly used as rocket engine and spacecraft structural parts. And the tungsten, molybdenum and their crystals are also used in space dynamical system. The order of the service temperature from high to low in refractory metals and their alloys is same as the melting point order of materials.
