Summary

Alumina coatings on Nicalon and C-Nicalon fibers were produced by a sol-gel process. The strengths of the as-received carbon-Nicalon fibers were retained even after the coated fibers were heated to 1000°C in air. Auger electron spectroscopy (AES), scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) methods were used to examine the coating and to investigate if there was any interaction between the coating and the fiber. A good interface coating was obtained by carefully controlling the dipping and heating processes.
