Development of refractory armored silicon carbide by infrared transient liquid phase processing …

The strength of the silicon carbide substrate was somewhat decreased as a result of the processing. Vapor deposition of tungsten prior to powder coating helped prevent this degradation. In contrast, molybdenum coating was more challenging than tungsten coating due to the larger coefficient of thermal expansion (CTE) mismatch as compared to tungsten and silicon carbide.

Handbook of Refractory Carbides and Nitrides | ScienceDirect

Refractory carbides and nitrides are materials with a high melting point, arbitrarily selected as greater than 1800°C and must have a high degree of chemical stability. Carbides and nitrides can be divided into several types depending on their different physicochemical structures and characteristics.
