Dry Sliding wear behavior of ABS Composites reinforced with nano Zirconia and PTFE

Abstract ABS composites reinforced with nano zirconia and PTFE have been prepared using melt compounding using twin screw extrusion. Dry sliding wear behavior of composites has been studied using pin-on-disc tribometer according to ASTM G99 standards. Experiments have been conducted in accordance with DOE by Response Surface Methodology (RSM). Load, Sliding Velocity,% of nano zirconia and% of PTFE has been considered as the input parameter, whereas response measured are wear and COF. Though the results show that addition of both fillers leads to reduction of wear, addition of PTFE reduces the wear significantly as PTFE acts as lubricant. By increasing load and sliding velocity, wear increases as well. A fuzzy logic based model has been developed to predict the wear of ABS composites and good agreement has been observed between experimental and predicted results. Optimization of process parameters in sliding wear have been obtained by using Desirability approach and the optimized parameters were found to be 2.5% of PTFE, 3% of zirconia, Load of 50N and sliding velocity of 2m/s.
