Abstract

This research work investigates the mechanical and dry friction wear behavior of the AA5022 matrix reinforced with nano-scaled particles. In this work, nano-scaled vanadium and tin were blended with an aluminum matrix, and the aluminum composite samples with different weight percentages of nano-scaled vanadium and tin at 0–10 wt.% range were fabricated through a muffle furnace and stir-casting techniques. The obtained results reveal the tensile strength and microhardness progressively increase with nano-scaled vanadium and tin addition in the aluminum matrix to 6 wt% of each. The wear loss and wear rate gradually decrease in the same samples. The internal structure of nano-scaled vanadium and tin reinforced hybrid aluminum composite samples was examined by scanning electron microscopy, which reveals that, sample C (6wt% of nano-scaled vanadium and tin particles) microstructure appeared uniform distribution and dispersed intensively in the aluminum matrix. The pure AA5022 was also studied to compare the mechanical and tribological properties. The sample C improved by 39% in tensile strength and improved by 22% in micro hardness. Moreover, hybrid aluminum composite samples showed improved wear-resistant characteristics, which can be used for various tribological applications, especially in electric automotive and modern aerospace.
