- Summary:
- The degradation of boron filament reinforced aluminum composites at temperatures over 400 C severely limits this material to relatively low-temperature applications. In order to extend the elevated temperature usefulness of such composites boron filament was coated with a diffusion and oxidation inhibiting coating of ?-silicon carbide. The coating was applied by thermally decomposing a halogenated silane compound on the surface of previously prepared boron filaments. Electron microprobe analysis showed that the boron had diffused part way through the silicon carbide layer during the deposition process at approximately 1200 C. The ultimate tensile strengths of the coated fibers, however, were found to be approximately the same as the uncoated fibers, namely, 450,000 to 550,000 psi
