Abstract

This research examines the effect of ceramic particulate of Si3N4 on the hardness, tensile, corrosion, and microstructure of reinforced AA8011 composites. The composites were developed by two steps stir casting process where both the particulates and the alloy matrix were preheated and melted respectively before mixing. 0%, 5%, 10%, 15%, and 20% Si3N4 particulates compositions were varied to fabricate the composites. Vickers microhardness tester was employed to study the hardness, the universal testing machine was used to analyze the ultimate tensile strength, the tribological performances of the developed composites AA8011- Si3N4 were analyzed under dry sliding condition using Universal Tribometer. The results of the experiment clearly revealed the improvement in the mechanical properties of the composites compared to the primary Al-Fe-Si alloy with excellent strength mechanism recorded at 20% reinforcement. Composites with 20% Si3N4 was found to have a better wear resistance hence, lowest wear rate.
