Abstract
Ceramic matrix composites were developed by powder metallurgy and the
blended matrix was reinforced with millscale particles from 3-18 wt.% at particles size
distribution of 106-250 µm. Microstructural, hardness and wear characterisations were
carried out on the composites using standardised methods. The results showed that the
106 µm millscale particles reinforced composite exhibited desirable hardness value of 124
BHN, low wear rate of 1.99 x 10-6 g/m and appreciable high wear resistance indicating
a potential for effective performance in service. The composites worn surfaces revealed
abrasion, adhesion and grooves formation. These features derived from the composites
microstructure formed the basis on which enhancement procedures could be developed.
