Rhenium (Re) metal has attracted as a promising refractory material to protect the components in high temperature rocket engines and hot gas valves because of its superior properties (high melting point of 3180 oC and high thermal shock resistance). Chemical vapor deposition (CVD), one of the vacuum methods, has been generally used for the fabrication of Re layer. However, CVD has some drawbacks such as complexity, high manufacturing cost, and high energy requirements. One possible alternative is an electro-spraying method (non-vacuum process), which could greatly reduce the manufacturing cost. In the present work, we have successfully deposited the Re thin film using the electro-spraying method. The influence of solution concentration and deposition time also investigated and discussed in detail. |
