ABSTRACT:
A carbide coating for a surface intended to be subjected to stringencies of temperature and erosion, such as rocket nozzles, turbine blades, heat shields, and hypersonic structures, formed on a carbon substrate from a halide of hafnium, silicon, tantalum or zirconium, followed by deposition from a said halide and a hydrocarbon. The layer has a high melting point, can be made very thin, and resists cracking and spalling.
