The invention comprises a process comprising infiltrating or infiltrating and coating a substrate with a boron-comprising precursor, and contacting the boron-comprising precursor with a nitrogen-comprising reactant to convert the boron-comprising precursor to BN or other a boron-nitrogen reaction product in the surface porosity or in the surface porosity and on the surface of the substrate. Composite materials comprising as one phase a substrate and BN or other a boron-nitrogen reaction product as a further phase, in surface porosity or in surface porosity and on a surface of the substrate, are claimed.

摘要:
Methods for making refractory metal and refractory metal carbide nanoparticle mixtures are provided. The nanoparticle mixtures can be painted onto a surface to be coated and heated at low temperatures to form a gas-tight coating. The low temperature formation of refractory metal and refractory metal carbide coatings allows these coatings to be provided on surfaces that would otherwise be uncoatable or very difficult to coat, whether because they are carbon-based materials (e.g., graphite, carbon/carbon composites) or temperature sensitive materials (e.g., materials that would melt, oxidize, or otherwise not withstand temperatures above 800 °C), or because the high aspect ratio of the surface would prevent other coating methods from being effective (e.g., the inner surfaces of tubes and nozzles). The nanoparticle mixtures can also be disposed in a mold and sintered to form fully dense components.
