Rhenium-metal carbide-graphite article and method |
| abstract |
A graphite-metal carbide-rhenium article of manufacture is provided, which is suitable for use as a component in the hot zone of a rocket motor at operating temperatures in excess of approximately 3,000 degrees Celsius. One side of the metal carbide is chemically bonded to the surface of the graphite, and the rhenium containing protective coating is mechanically bonded to the other side of the metal carbide. Rhenium forms a solid solution with carbon at elevated temperatures. The metal carbide interlayer serves as a diffusion barrier to prevent carbon from migrating into contact with the rhenium containing protective coating. The metal carbide is formed by a conversion process wherein a refractory metal carbide former is allowed to react with carbon in the surface of the graphite. This structure is lighter and less expensive than corresponding solid rhenium components. |
