Effect of Single, Double and Triple Particle Size SiC and Al2O3 Reinforcement on Wear Properties of AMC Prepared by Stir Casting in Vacuum Mould

摘要

The aim of present research work is to study the effect of single particle size (SPS), dual particle size (DPS) and triple particle size (TPS) of SiC and Al2O3 reinforcement as hybrid solute on wear properties of aluminium matrix composite (AMC) prepared by stir casting in vacuum mould. The ABS plastic based master pattern (prepared with fused deposition modelling setup) for vacuum mould has been used in the present study. The friction and wear tests were carried out using a pin-on-disc type tribo-test machine under dry sliding condition. The results of study suggest that SPS based AMC exhibited better wear resistant properties as compared to DPS and TPS. The study also highlights the effect of other controllable process parameters of vacuum moulding process (namely: vacuum pressure, sand grain size and proportion of solutes) on wear behavior of AMC.
