Production and wear characterisation of AA 6061 matrix titanium carbide particulate reinforced composite by enhanced stir casting method

Metal matrix composite (MMC) focuses primarily on improved specific strength, high temperature and wear resistance application. Aluminium matrix reinforced with titanium carbide (Al-TiCp) has good potential. The main challenge is to produce this composite in a cost effective way to meet the above requirements. In this study Al-TiCp castings with different volume fraction of TiC were produced in an argon atmosphere by an enhanced stir casting method. Specific strength of the composite has increased with higher % of TiC addition. Dry sliding wear behaviour of AMC was analysed with the help of a pin on disc wear and friction monitor. The present analyses reveal the improved specific strength as well as wear resistance. (C) 2011 Elsevier Ltd. All rights reserved.
