Dry sliding wear behavior of Mica, Fly Ash and Red Mud particles reinforced Al7075 alloy hybrid metal matrix composites

Received Date:18 November 2020, Accepted Date:20 January 2021, Published Date:02 February 2021


Objective: To synthesize and evaluation of wear behavior of mica. The effect of mica, fly ash and red mud particles reinforced Al7075 alloy composites. Method: The hybrid composites were prepared with constant 1 wt. % of red mud particles and varying weight percentages of mica (2, 4 and 6 wt. %) and fly ash (1, 3 and 5 wt. %) particles in Al7075 alloy by stir casting method. Findings: The synthesized multiple particles reinforced Al7075 alloy hybrid composites were subjected to microstructural studies and wear properties testing. Microstructural characterizations of obtained samples were carried out by scanning electron microscopy and XRD patterns. The mica, fly ash and red mud particles were evenly distributed and presences of these particles were confirmed by the XRD patterns. Novelty /Improvement: Al7075 alloy with red mud, fly ash and mica particles reinforced hybrid composites were exhibited the superior wear resistance. Various wear mechanisms were observed in the Al7075 alloy with mica, fly ash and red mud composites using SEM.
