Research Progress of Rhenium prepared by chemical vapor deposition

Abstract:

Rhenium is widely used as functional materials and ultra high temperature structural materials due to its excellent physical and mechanical properties. A variety of methods has been applied to prepare rhenium materials, in which chemical vapor deposition (CVD) is one of the main technique. The reaction type, deposition condition and effect of rhenium by CVD are briefly introduced firstly in the present paper. Then, the deposition dynamics, microstructure characteristics, mechanical properties and typical applications of CVD rhenium are reviewed, and compared with powder metallurgy rhenium. Finally, several key issues which need to be solved hereafter are put forward, and the directions of further research and applications foreground is prospected.
