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.
