Laser Probe Vaporization/Oxidation Testing of High Temperature Composites

Abstract

A laser probe technique for the determination of vaporization/ oxidation processes of high temperature ceramics was investigated. The technique was found to provide meaningful data on the vapor species near the specimen surface. These data were correlated with changes in specimen microstructure and analyzed by thermochemical and kinetic modeling. Results were found to be in general agreement with the modeling. Keywords: Laser probe, Vaporization, Oxidation ceramics.
