Aim: This study compares the surface roughness of Al-Mg-Cr alloys with novel nano WC (Tungsten carbide) reinforced Al-Mg-Cr alloys composites.
Materials and Methods: A rectangular plate with a thickness of 10mm and a length of 120mm of reinforced Al-MgCr alloy nanocomposites and unreinforced aluminum alloy synthesized using stir casting method was used in this research.The drilling was performed with HSS drills of diameter 8mm, and the surface roughness test was conducted according to ASTM standards.In both experimental and control groups, there are 20 test samples each, with g-power 80% used for calculating sample sizes.A significant difference between the synthesized composites and the as-cast alloys was revealed to be P=0.001(p<0.05).
Results: The surface roughness values are calculated for 20 samples of both as cast Al-Mg-Cr alloys and inclusion of 2wt% WC ceramic strengthening particulates nano composites.The minimum surface roughness values obtained for both samples are 3.89µm and 8.06µm respectively.
Conclusion: Within the limitations of present study, it was observed that the inclusion of hard novel nano WC ceramic particulates slightly increases the surface roughness 3.89% in comparison with as cas Al-Mg-Cr alloys.
