Influence of load and sliding speed on wear behavior of AZ91E magnesium alloy nanocomposite by dry sliding

The usage of magnesium alloy has grown in the field of automotive, aviation, and marine sectors due to its significant characteristics of lightweight, high specific strength, impact, and wears resistance. The present investigation is to evaluate the wear characteristics of magnesium AZ91E alloy nanocomposite with SiCnp by pin-on-disc wear tester using dry sliding conditions. The dry sliding wear investigations were carried out on a 200 m constant sliding distance with a load of 10 N, 20 N, 30 N, and 40 N at various sliding speed (0.25 m/sec to 0.75 m/sec). The wear rate of nanocomposites significantly decreased with the normal load at a high sliding speed of 0.75 m/sec as compared to AZ91E alloy. The result showed that the coefficient of friction has gradually increased with increase in the load 10 N to 40 N at different sliding speed. It has varied from 0.307 to 0.472. (c) 2020 Elsevier Ltd.
