Synthesis and abrasive wear performance of stir cast AA6063-TiC composite materials

Abstract

Typically Aluminum 6063 matrix composites have an extensive wear resistance application due to its high specific strength. Here the stir casting fabricated composites having 0, 3, 6 and 9 wt% of titanium carbide (TiC) are tested using a pin on disc sliding wear test equipment. Loads (P), speed (sliding and rotation) and sliding distance (D) are the input parameters. The improvement in hardness was observed when TiC content increases due to the homogeneous dispersion strengthening mechanism. The incorporation of TiC in the AA6063 matrix reduces the rate of wear (WR) and increases the resistance to wear. The “COF” reduces when the TiC composition increases. The “WR” and COF increase when ‘D’ and ‘P’ increases for all the compositions tested.
