A detailed study on the processing of Al-metal matrix comp, cites with the reinforcement of different parti-culates such as SiC, TiN and Ti02 was carried out. The Al-SiC composite powder prepared through atomisation route is expected to limit the interfacial reaction bet-ween the matrix and the ceramic particulate and help in making customer tailored components by powder metallurgy route. An attempt to avoid the interfacial reaction of matrix and ceramic is investigated by impregnating the Al matrix with TiN particulates. Similarly, Al-Ti02.composite is investigated by new spray forming technique, where the interfacial reaction between Al and Ti02 is expected to form intermetallic compounds and improve the bonding and mechanical properties. The results of the present studies show that the Al based composites prepared through various techniques exhibits excellent mechanical, physical and tribological properties and could emerge as promising materials for defence, aerospace and other engineering applications.
