초록

A method of making heat engine components, such as rocket nozzle throats, includes forming a body having at least one surface, wherein the body is made of a refractory metal, and compressing a ceramic powder between a die and the at least one surface of the body, with sufficient heat and pressure to densify and thus form a solid ceramic coating on the at least one surface of the body. Nozzle throats made according to the invention have bodies made of refractory metals, such as tantalum, and ceramic coatings on the inner surfaces of the annular bodies, wh...

1. A rocket nozzle venturi throat comprising: a tantalum refractory metal ring having a generally annular shape and a central passageway defined by an inner surface; and a ceramic layer diffusion bonded to the inner surface of the metal ring, the ceramic layer being formed of a material consisting essentially of a carbide, wherein the carbide is a composition of tantalum carbide and tantalum2carbide; and a diffusion bond region comprising a transition between the refractory metal ring and the ceramic layer. 2. A rocket motor comprising: a body ...
