Abstract
In this study the wear behaviour of three grades of alumina ceramic material was investigated. The experimental procedure was found to influence the accuracy of data collection and data analysis. Materials with a higher grain size were found to have better wear behaviour. A pseudo-toughening phenomenon takes place at high temperatures as a result of grain rearrangement and subsequent local decrease in residual stress. The grain boundaries are important microstructural elements which control decisively the tribological properties of alumina based ceramic materials. The intergranular mode of fracture dominates the wear damage phenomena.
