  • Abstract:
  • This study investigates the dry sliding wear behavior of Mg-Al/Mg2-Si composites reinforced with varying percentages of Bismuth (0%, 0.7%, 1.4%, and 2%). Using the Design of Experiments (DOE) method and the Taguchi approach with an L9 orthogonal array, the influence of load, sliding speed, and sliding distance on wear loss was examined. Experimental results were analyzed using Analysis of Variance (ANOVA) to determine the significance of each parameter on wear behavior. The results indicate that for the composite with 0% Bismuth, load was the most significant factor influencing wear loss, with a contribution of 39.54%. For the composite with 0.7% Bismuth, sliding speed was found to be the most significant factor, contributing 64.4%. In the composite with 1.4% Bismuth, sliding distance was the most influential parameter, accounting for 46.3% of the variation in wear loss. Lastly, for the composite with 2% Bismuth, load again emerged as the most significant factor with a 43.2% contribution. The study concludes that the wear behavior of Mg-Al/Mg2-Si composites is significantly influenced by the applied load, sliding speed, and sliding distance, with their effects varying depending on the percentage of Bismuth reinforcement. These findings provide valuable insights into optimizing wear resistance in composite materials through tailored adjustments of wear parameters.
