Abstract:
1. A method of manufacturing a refractory metal composite article having a refractory metal ceramic section and a refractory metal ceramic coating that form a composite porous matrix, the method comprising: (a) at least partially filling pores within the refractory metal composite article with a solid filler to thereby reduce a porosity of the refractory metal composite article, each of the refractory metal ceramic section and the refractory metal ceramic coating including at least one of a refractory metal carbide, a refractory metal silicide, or a refractory metal boride such that the refractory metal ceramic coating is disposed directly adjacent to the refractory metal ceramic section, and further including depositing a pre-ceramic polymer into the pores and converting the pre-ceramic polymer to a ceramic material.
