E XPERIMENTAL DETAILS

Materials n the current work, Al6061 aluminium alloy functioned as the matrix and was augmented with nano Al 2 O 3 and nano ZrO 2 . Supplier Name: Nano Research Lab The raw material was analyzed with Energy Dispersive X-ray Analysis equipment (EDAX) to confirm its chemical makeup. Tab. 1 delineates the constituent composition of the Al6061 alloy, whereas the SEM and EDAX plot reveals peaks corresponding to the base alloy, Al 2 O 3 , and ZrO 2 , as illustrated in Fig. (1-6) respectively.
