Oxidation properties and Joining of Rhenium on C/SiC composites using Titanium interlayer. |
| 초록 |
Re alloys are refractory metal with its high melting point and has an unique combination of physical and chemical properties. W-Re alloys coatings are applied to enhance heat resistance and endurance of components and also to protect them from corrosion, which makes it an ideal material for application in various fields such as high temperature structural materials, heat exchanger, and heat protector for space shuttle and missile thrusting systems. In this study, Re is successfully bonded to C/SiC composites with Ti interlayer by hot pressing. Ti interlayer has diffused into the substrate to form carbide intermediate phases to enhance bonding strength and also the layer brazed with Re metal. Residual Si in C/SiC composites has diffused into Re metal, deteriorating the thermal properties at high temperature of 2000 oC. Oxidation tests are performed using an oxyacetylene torch on samples having different joining conditions. The mechanical properties such as bonding strength have characterized and analyzed with the microstructure of the interfaces. The interlayers are characterized by XRD, SEM and TEM.
