Abstract

Abstract: The multi-mode microwave system and conventional sintering were carried out. Properties of Al₂O₃-ZrO₂ composites were investigated, relative wear
mechanisms were proposed with regard to the processing approaches. Compared with the conventional results, microwave processed ZTA ceramics appear with the
improved relative density, fracture toughness and bending strength, the developed microwave structure, and the ameliorated wear resistance. The wear for the conventional
ZTA specimens are mainly caused by the shovel of the interface grains, the porosity is filled by the debris and the smooth wear track is achieved; whereas interface grains
in microwave specimens are basically swept out. The incremental loads accelerate the wear.

Key words: microwave, conventional, ZTA, Wear
