Abstract: An investigation on ZA-27/Al2O3 Composites processed by centrifugal casting technique was carried out to study wear characteristics of reinforced particles on the base alloy. Operating parameters such as size of reinforced alumina particle (20-100 m), location of specimen from the center of pin-on disc apparatus (0- 40 mm), melting temperature of the melt (450-650 C), wt. % of alumina added (5- 25), sliding speed (100 - 500 rpm) and normal wear load (10 - 50 N) were concentrated. Taguchi technique with notation L25 was chosen for the analysis. It was noticed that, normal wear load is one of the most influencing factors on wear rate and has the highest influence on the dry sliding wear of composites followed by sliding speed, wt. % of Al2O3, specimen location, particle size and melting temperature.

Key words: alumina particles, centrifugal casting, Taguchi Technique, Wear behaviour, ZA-27 alloy.
