Abstract

The vital focus of the research is intended in examining the aspect that impact the rate of wear for a hybrid aluminium metal matrix composite. The percentages of two reinforcements that are employed, the weight, and the sliding speed are the variables taken. The procedure entails employing the vortex-stir casting process to produce the hybrid composite. Utilizing a pin-on-disc apparatus, the fabricated composite materials are evaluated in compliance with the ASTM G99 standard. The test settings embrace varying weights and sliding speeds ranging from of 10 N to 30 N and 1 m/s to 3 m/s via Response Surface Method. The acquired rate of wear findings of the composites was examined for the utmost significant parameter, which was observed as sliding speed, followed by the load. The load factor was the solitary factor that had an impact in both the linear and square terms, whereas the weight fractions of the cenosphere and molybdenum disulphide had the minimum bearing effects. The wear percentage is primarily influenced by the combinative influence of the weight fraction of cenosphere – weight fraction of molybdenum disulphide, load – weight fraction of molybdenum disulphide, weight fraction of molybdenum disulphide – sliding speed and load – sliding speed. Despite their relatively small percentage contributions, cenosphere and MoS2 have been discovered to have a significant outcome on the wear rate of composite materials. The rate of wear also tends to decrease as cenosphere, and molybdenum disulphide weight percentages raise.
