Abstract
The current study aims to investigate the tribological behaviour of aluminium (AA2024) alloy composites reinforced with boron carbide (B4C) particles. The Stir casting technique was used to fabricate the composites. The percentage reinforcement content was varied from 0 to 4% by weight in steps of 1%. A pin-on disc wear testing machine was used to evaluate the wear loss of composites. The dry sliding wear tests were carried out to evaluate the wear behavior of the AA2024 alloy and its composites. A plan of experiment generated through Taguchi’s technique is used to conduct experiments based on L25 orthogonal array. The sliding wear tests were conducted for various loads ranging from 10 to 50 N, sliding velocities ranging from 1.5 to 7.5 m/s and sliding distances ranging from 500 to 2500 m. Analysis of variance (ANOVA) was performed to determine the effect of individual factors on the wear loss and coefficient of friction. The results revealed that load and sliding distance are directly proportional to the wear rate and % reinforcement and sliding velocity are inversely proportional to the wear rate of the composite material. The incorporation of B4C particles in AA2024 alloy improves the tribological traits.
