Abstract

We report on the use of TiC particles as high temperature healing agent in alumina based composites. The selection of TiC was based on a theoretical analysis of its high temperature stability in contact with Al₂O₃, its volumetric expansion upon oxidation and the adhesion between the reaction product TiO₂ with Al₂O₃. Fully dense 15 and 30 vol.% TiC-Alumina composites were made by Spark Plasma Sintering. Initial damage was produced by Vickers indentations. The strength recovery was determined for temperatures between 400 and 800 °C. The mechanical measurements were complemented by microstructural characterization of the base material and the healed cracks.
