Abstract: Alloying was conducted on Al 7075 alloy by reinforcement of the metallic portion of molybdenum (Mo) in powder blended with dielectric fluid to strengthen wear resistance and investigate the lubing features of this woven surface. The present work features alloying of Al 7075 with Mo as a vital material. Mechanical attributes along with powder frustration and layered coating size and shape were investigated by scanning electron microscope (SEM), energy dispersive X-ray analysis (EDXA), optical microscope (OM), surface texture with roughness tester and wear vision using pin on disc device. The effect of Peak current (A), Pulse on time (Pon) and Pulse off time (Poff) on the wear execution of an alloyed discharge, Al 7075 auxiliary materials have also been considered using Response Surface Methodology (RSM). Analysis of Variance (ANOVA) was interpreted to add to the effectiveness of material variables on the performance characteristics. Confirmation tests were performed to compare the predicted values with the experimental values and it was found that the results matched well with the experimental results.
Keywords: Electrical Discharge Alloying, Surface Roughness, Specific Wear Rate, Coefficient of Friction, RSM Technique.
