EFFECT OF BAGASSE ASH REINFORCEMENT ON THE WEAR BEHAVIOUR OF Al-Cu-Mg/BAGASE ASH PARTICULATE COMPOSITES Aigbodion V. S, Hassan S. B, Ause.T and Nyior.G.B Department of Metallurgical and Materials Engineering, Ahmadu Bello University, Samaru, Zaria, Nigeria. E-mail, aigbodionv@yahoo.com Abstract The effect of Bagasse ash (BAp) particles reinforcement on the wear behavior of Al-Cu-Mg alloy has been studied. Bagasse ash particles were varied from 0–10wt. % with interval of 2wt%. Unlubricated pin-on disc tests were conducted to examine the wear behaviour of the aluminium alloy/ Bagasse ash particulate composites. The tests were conducted at varying loads, from 5 to 20 N and sliding speeds of 1.26 m/s, 2.51m/s, 3.77m/s and 5.02m/s for a constant sliding distance of 5000 m. The results showed that the wear rates of the Al-Cu-Mg/ BAp composites are lower than that of the matrix alloy and further decrease with increasing Bagasse ash content. Wear increase as the sliding speed and applied load increases with decreased in co-efficient of friction. The microstructure of the worn surface revealed that a large amount of plastic deformation was observed on the surface of the unreinforced alloy. While Bagasse ash reinforced Al-Cu-Mg alloy showed worn out surfaces that are not smooth, with grooves, scratches and parallel lines were observed. A combination of adhesion and delamination wear was in operation. These results show that improve wear properties is achievable in the aluminium alloy by the addition of Bagasse ash particles as reinforcement material.

Abstract:

The effect of Bagasse ash (BAp) particle reinforcement on the wear behavior of Al-Cu-Mg alloy has been studied.  Bagasse ash particles were varied from 0 wt pct-10 wt pct with interval of 2 wt pct. Unlubricated pin-on disc tests were conducted to examine the wear behaviour of the aluminium alloy/Bagasse ash particulate composites. The tests were conducted at varying loads, from 5 to 20 N and sliding speeds of 1.26 m/s, 2.51 m/s , 3.77 m/s and 5.02 m/s for a constant sliding distance of 5000 m. The results showed that the wear rates of the Al-Cu-Mg/BAp composites are lower than that of the matrix alloy and further decrease with increasing Bagasse ash content. Wear rate increases as the sliding speed and applied load increase. The microstructure of the worn surface revealed that a large amount of plastic deformation appeared on the surface of the unreinforced alloy. While Bagasse ash reinforced Al-Cu-Mg alloy showed worn out surface that is not smooth, and grooves, scratches and parallel lines were observed. A combination of adhesion and delamination wear was in operation. These results show that improve wear properties is achievable for the aluminium alloy by the addition of Bagasse ash particles as reinforcement material.
