The Abrasive Wear of Alumina Matrix Particulate Composites at Different Environments of Work
The paper presents the results of investigation on the wear of alumina-based composites containing submicrometre particles of other phases in different conditions of work. Three types of phases were used as additives: tungsten carbide, yttria stabilized zirconia and metallic tungsten. The above mentioned phases were used separately or simultaneously as mixes. Two types of tests were performed - the Dry Sand Test and the Miller Test in wet pulp. Coarse silicon carbide grains were used as an abrasive medium in both cases. The results indicate that the optimal wear susceptibility in given work environment could be achieved by the addition of different type of additives.
