Evaluation of Corrosion Behavior, Shear Stress Response, and Microstructural Characteristics of Hybrid Aluminium Metal Matrix Composites Reinforced with TiO₂ and MoS₂
Abstract
In recent years, hybrid aluminum metal matrix composites (HAMMCs) demand increased for engineering application and in harsh environments such as marine and aerial buildings. In this study, Al7075 alloy was used as the base matrix and titanium dioxide (TiO₂) and molybdenum disulfide (MoS₂) used as reinforcement material. The aim was to investigate the corrosion resistance, shear strength and microstructural characteristics of the synthesized Al7075 materials. In this research work composites were made using the melt-cast process and placed in a series of tests. Corrosion testing, Shear strength measurement, and microstructural analysis with a Scanning Electron Microscope (SEM) performed in this research work. The results showed that the combination of TiO₂ and MoS₂ improved corrosion resistance and shear strength. Observed that the distribution of particles of reinforcement is uniform. It will help to improve the efficiency of the design and mechanical work. Overall, these findings show that hybrid reinforcement improves the strength and durability of Al7075 composites. In corrosive environments it makes them suitable for load-bearing applications. These materials (Al70750) are commonly used in the aerospace, marine, and also used where superior strength is required.
