<p>The sliding wear properties of aluminum toughened with nano alumina particulate in a metal matrix nanocomposite have been justified via this work. Non-contact cavitation procedure implemented for the exclusive fabrication of nanocomposite material. In this observation, an unlubricated Multiple Tribo Tester has been installed to recognize the wear properties of an aluminum-backed nanocomposite. Two loads, i.e., a constant load and a load varying stepwise while keeping speed and time constant, have been introduced to conduct the sliding wear test on the system. The very consequences of the above setup reveal that, with the corresponding rise in parameters, i.e., load and speed, the wear rate also rises. A Field Emission Scanning Electron Microscope has been introduced into the system to observe the impacted, wear-out surfaces of both specimens, i.e., unpolluted aluminum and MMNC, and determine the wear mechanism. To optimize wear rate, the Novel Remora Wear Reduction Model (RWRM) was proposed; it is based on the principle of remora optimization. The observation established that amongst the specimens, MMNC exhibits enhanced resistance to rubbing wear; therefore, abrasion and delamination are considered as profound wear mechanisms.</p>
