Summary

Sic fibers were prepared with boron nitride (BN) coatings using an in-situ processing method. Scanning Auger electron spectroscopy, X-ray photoelectron spectroscopy, and transmission electron microscopy showed that the coatings were uniformly distributed, well-crystallized, hexagonal BN. The coated fibers had high strength (∼ 3 GPa) and excellent creep resistance based on bend stress relaxation tests.
