BORON CARBIDE COATING.

摘要

A fiber is coated with boron carbide by contacting the fiber with a reaction mixture of a boron source and a carbon source at a temperature of at least about 1050 DEG C. such that the boron source and carbon source react with each other to produce a boron carbide coating on the fiber. The fiber comprises aluminum oxide, SiC, or Si3N4 and the boron carbide coating comprises up to about 40 atomic percent boron.
