Rhenium
Rhenium coatings and freestanding structures enable parts to survive and outperform other materials in solid rocket motor applications at temperatures approaching 5756°F (3180°C).
Advantages
- High melting point: 5756°F (3180°C)
- No ductile-to-brittle transition temperature
- Endothermic oxidation at high temperature
- Resistance to water vapor
- Zero erosion in solid propellant environments
- Stable contact with carbon, molten alkali metals, oxides, and glasses
- Ability to protect carbon, carbon/carbon, molybdenum, and tungsten alloys from oxidation, wear, and corrosion
- Excellent wear resistance
