Influence of Factors on Wear Resistance Property in Aluminum Surface Composite by Friction Stir Processing
Keywords:Aluminum surface composite, Friction stir processing, Wear Resistance
This research aims to study the influence of factors on wear resistance property in aluminum surface composite grade 5052 with 18-micron silicon carbide reinforcement by friction stir processing. Comparison of the process parameters, such as the high rotational speed at 1,500 rpm, constant and then using the low traverse speed at 10 mm / min and the number of pass at 2nd pass (S2F1R1) compare with the high traverse speed at 30 mm / min and the number of pass at 4th pass (S2F2R2). The results showed that the low traverse speed at the two passes of stirring is enough to have the dispersion of the powder particles regularly and the fracture of the powder particles spread throughout the stirring area, resulting in higher wear resistance properties. It offers the lowest wear rate of 0.1088 mm3 / Nm, 3.4 times the wear resistance of aluminum A5052. In addition, the low traverse speed at 10 mm / min and the number of pass at 2nd pass (S2F1R1) takes slightly different production times with the high traverse speed at 30 mm / min and the number of pass at 4th pass (S2F2R2) but offers a much lower rate of wear.
