Effect Multiple Addition (TiO₂ and Fly Ash) on Wear Behavior and Hardness of 2024 Al Alloy

Abstract:

This research is devoted to study the effect of addition (2%) TiO₂ with different weight percent of fly ash particulate (0, 2, 4, 6%) to 2024 Al alloy on the wear behavior and hardness. The alloy was fabricated by the liquid metallurgy method. The results founds that the wear rate decreased from 0.55 with 0% fly ash to 0.18 at addition percentage of 6% fly ash. Also, the results reveal increasing the samples wear rate with increasing the load and loaded time. The rate of wear was decreased with increasing the sliding speed. Also, the values of hardness increased from 120VH to 160VH with rising the fly ash from 0% to 6%. Keywords: Fly Ash addition, TiO₂, 2024 Al Alloy, Wear Resistance, Hardness.
