The paper interprets the tribological behavior of 20% silicon carbide and various weight percentages of multiwall Carbon Nanotubes (CNT) reinforced on aluminum through powder metallurgy. The hardness testing was done on Brinell hardness tester. The sliding wear tests without lubrication were carried out on fabricated composites utilizing 'pin-on-disc' tribometer equipment under variation in sliding velocity, applied load, sliding time and CNT weight percentage. Taguchi's L27 orthogonal array was used for Design of Experiments (DOE), and analytical modeling of fabricated composites was done. The result was converted into Signal-to-Noise (S/N) ratios. ANOVA was used to determine the decisive design parameters considerably influencing the wear rate of the composite material. A regression equation created a relationship between decisive parameter generated from ANOVA model. In order to demonstrate regression equation, validation wear behavior study was conducted. The error involved in between investigated value from experiment and predicted values of the regression analysis for fabricated composites was around 9.0%. The results indicate that for dry sliding wear analysis, CNT, load, sliding time and sliding velocity have great effects on wear behavior of composites.
Materials that have high strength/weight ratio, high specific rigidity, corrosion resistance and excellent wear properties are essential in most of the structural engineering applications typically in automobile, ship, steel and aeroplane industries. These attractive properties are not from monolithic material; however, they can be procured by reinforcements ceramics, polymers, organic materials with base metal matrix with reinforcements such as ceramics, polymers and organic materials. Such materials are known as Metal Matrix Compounds (MMC). Composites that have an aluminum alloy as base matrix are known as hybrids. Aluminum-MMC are widely used in aeroplane, automotive, sports, etc. The production of these composites involves many tasks such as the uneven scattering of the reinforcement, porosity formation and poor wettability. Many researchers have expressed recently that the reinforcement uniform scattering can be obtained by monitoring the procedure considerations.
