Abstract

The mechanical properties and thermal shock behavior of the hot pressed alumina matrix ceramics, with added 6 vol. % tungsten carbide particles, was investigated. The thermal shock resistance of the materials was evaluated by water quenching and subsequent three-point bend testing of flexural strength diminution. The hot-pressed composite exhibited 70°C higher temperature differential of thermal shock resistance than the monolith, as well as increased flexural strength and fracture toughness. The calculation of thermal shock resistance parameters for the composite and the monolith gives a possible explanation for the differences in thermal shock behaviour.
