Abstract: Wear behaviour of AA6061-B4C and AA6061-B4C-Gr composites fabricated by stir casting process was investigated by performing the dry sliding wear test using a Pin-on-disc wear testing equipment. The influence of parameters such as material, sliding load and sliding velocity on the wear loss of specimens was investigated. Experiments were conducted based on the L9 Taguchi’s technique. It was found that the sliding velocity was the most dominant factor influencing the wear loss followed by sliding load and material. Finally, confirmation tests were carried to verify the experimental results.
