Comparison study on dry and wet sliding wear behaviour of aluminium/nano composites

Abstract

In the present study, the dry and wet behaviour of aluminium/Nanocomposites is evaluated using a pin on disc method under the dry and wet conditions. Aluminium/Nanocomposites were fabricated by ultrasonic cavitation stir casting process. The wet wear test was carried out using lubricating oil SAE 20W 50. Wear behaviour of Nanocomposites was evaluated by different loading conditions such as 15N, 30N, 45N and 60N with constant sliding speed. The wear surfaces were analysed by scanning electron microscope. The test revealed that the wear rate in increased with applied load and also more wear is observed in dry condition when compared with wet condition.
