Comparative Study and Optimization of Dry Sand Abrasive Wear Behavior of As-Cast and Retrogression and Re-Aging of 7075 Aluminum Alloy using Taguchi and ANOVA
Jagannath, Hemavathy S
For the past many years 7075 aluminum alloy widely used in aircraft structural parts where high wear resistance are required wear rate are reduced by the retrogression and re- aging heat treatment (RRA). Three body sand abrasive wear test is conducted on both as-cast and retrogression and re-aging specimens as per Taguchis experimental design and L9 orthogonal array wear parameters like time, load, and speed are considered and track diameter kept constant it is found that when wear resistance of retrogression and re-aging heat treated (RRA) specimen is more as compared to the as-cast specimens. The design of experiments (DOE) approach using taguchi method was employed to analyze the abrasive wear behavior of material. Signal-to-noise ratio and analysis of variance (ANOVA) were used to investigate the influence of parameters on the wear rate and also determine the optimal parameters for minimizing the wear rate.
