Wear analysis of Al7075 alloyed with nano B4C: A taguchi approach

The paper discusses about a novel combination of Aluminium 7075 reinforced with Boron Carbide (B4C) in nano form in terms of wear behavior. This type of composites are popular now a day's addressing various needs of industry especially where the weight, mechanical and wear properties of the alloy have a significant effect on end application. The present investigational work involves base metal Aluminium 7075 reinforced with B4C in nano form in various percentages by weight (3 to 12%). The specimens were prepared by stir casting process as per ASTM standards and were tested for their behavioral aspects towards wear using pin on disc. The taguchi approach was applied to optimize the process parameters for the case. The process has four factors, four levels considering, composition of nano B4C as 3%,6%, 9% and 12%, load variations in steps are 10, 20, 30 and 40 N, speeds selected are 100, 200, 300, and 400 rpm respectively and sliding distances preferred are 500,1000,1500 and 2000 m to study the effects on wear. Post experimentation analysis established that the presence of nano B4C particles has shown considerable reduction in wear with the samples. (c) 2021 Elsevier Ltd. All rights reserved.
