High Temperature Properties of Ceramic/Carbon Systems in an Oxidizing Environment

Abstract

The objective of our research is to indentify and learn to constructively modify the features of the bonding interactions that lead to brittleness in carbon-based ceramic materials. We have been examining the titanium/carbon and tungsten/carbon systems, both the naturally occuring carbides and artificially constructed superlattices. We are examining the question of whether artificially constructed multilayer (superlattices) structures offer an advantage over the naturally occurring crystalline structures in maintaining high temperature mechanical stability in an oxygen- containing environment. This related to the modification of the type of bonding, metallic versus covalent, possible by making artificial structures and how this affects brittleness and hence fracture behavior.
