Al 4043 alloy is extensively used as a filler material for welding aluminum alloys, especially when welding alloys from the Al 6000 series. It is utilized in aerospace and automotive structural components. For longer life in automotive applications, the wear resistance of Al 4043 alloy must be improved. According to research, tungsten carbide has good wear resistance. In this research, Al 4043 alloy is reinforced with varying percentages (1, 3, and 5%) of nano-sized tungsten carbide to increase wear resistance. Taguchi L27 orthogonal array is employed for the wear analysis. The Taguchi signal-to-noise ratio is used to determine the optimal parameters for minimizing wear and coefficient of friction. The regression model and artificial neural network are developed to predict the experimental results. The outcomes of the regression model and artificial neural network are compared to the experimental results to demonstrate both models’ efficacy. A confirmation test was carried out for the optimal process parameter. The result shows that the minimized specific wear rate of 0.12 mm3/Nm, coefficient of friction of 0.01, and frictional force of 1.02 N are achieved at the optimal combination.

Nowadays almost all the industries around the globe are using the composites instead of ferrous alloys to produce the low weight mechanical elements/components without scarifying the properties of the materials being used. The aluminium is a best substitute to conventional materials due to their ‘low weight’, ‘corrosion resistance’, ‘high strength’ and ‘low density’ properties/ characteristics. Aluminium Metal Matrix (AMM) composites are the trending materials to be used in various engineering applications having the capacity to accomplish the required demand. The specific/ desired properties can be obtained by adding the reinforcement fillers like SiC, TiC, B4C, Tungsten Carbide, Fe, stainless steel, Oxides, Nitrides, Molybdenum Disulphide, fly ash, Graphite, red mud, Agro waste powders like coconut shell ash (CSA), rice husk ash (RHA), palm kernel shell ash (PKSA), bagasse ash, maize stalk ash, been shell waste ash, Bamboo leaf ash, corn cob ash, aloe Vera powder, Egg shell ash and snail shell ash etc., to the Aluminium matrix material. Many researchers have studied the effect of reinforcing materials to the Aluminium matrix to enrich the ‘metallurgical and mechanical’ characteristics with the modification in texture and surface of the composite. The present review article aims to study the technique of stir casting to fabricate Al-7075 based metal matrix and hybrid composites with the incorporation of above reinforcement particulates and how the addition of above reinforcing materials to Al-7075 matrix has enhanced the properties like compressive strength, impact strength, hardness, fracture toughness, wear resistance and corrosion resistance with the reduction in density of composite. The influence of type, size and shape of the reinforcing materials on characteristics of Al-7075 metal matrix composites and the possible reasons of increase/decrease in physical/ mechanical characteristics are studied.

The study investigates the mechanical, and tribological properties of Al6061-SiC-NSA hybrid composites. The characterization via FE-SEM reveals NSA particle’s crystal structure and agglomeration, with an average particle size of approximately 400 nm. The EDS analysis confirms the presence of oxides (TiO2, SiO2, Fe2O3, Al2O3) along with calcium and potassium. The XRD spectra corroborate these findings, additionally identifying Calcite and intermetallic compounds. The Al6061-5SiC-10NSA composites has improved compressive strength of 254 MPa compared to 220 MPa for base Al6061 alloy. The tensile strength of base Al606 (100 MPa) decreased to 70 MPa for Al6061-5SiC-20NSA composites. The tensile strength decreases with increasing NSA content. Fracture analysis indicates ductile fracture mechanisms, supported by FE-SEM images displaying honeycomb-like structures and dimples. Impact testing reveals reduced impact strength in composites compared to Al6061 (26J3), with Al6061-10SiC-5NSA exhibiting the best toughness of 22.5 J3. Density decreases in composites, with density of Al6061-5SiC-20NSA composites has reduced to 2.40 g/cm3. The microhardness of Al6061-10SiC-5NSA has better value of 109 HV, whereas further addition of NSA has resulted in decrease in microhardness of composites. Pin-on-disc wear tests demonstrate improved wear resistance with increased NSA content, with Al6061-5SiC-20NSA outperforming other compositions. COF decreases with increased NSA content and sliding speed. FE-SEM analysis of worn surfaces reveals that the major wear mechanism is adhesive wear followed by delamination, further the oxide formation along the surface aiding wear resistance of the composites. Tafel testing indicates decreased corrosion potential with increased NSA content, with Al6061-5SiC-20NSA exhibiting improved corrosion resistance.
