Development of Aluminum-Based Metal Matrix Composite for Dry Bearings Reinforced with Titanium Dioxide and Silicon Carbide

Metal matrix composites (MMCs) have evoked a keen interest in recent times for their potential applications in automotive and aerospace industry components. One such particulars include dry sliding bearings, which have widespread applications in various industries due to their self-lubricating properties, high wear resistance, and low maintenance requirements. The wear as a consequence of metal-to-metal friction can have a detrimental effect, expediting malfunctions or much more adverse spin-offs on the whole system. This study focuses on the development and characterization of a novel dry bearing material composed of a MMC consisting of aluminum (Al), titanium dioxide (TiO₂), and silicon carbide (SiC). Tribological tests revealed a low friction coefficient, ensuring efficient and reliable operation. The results indicate the enhancement of MMC’s performance and durability in dry bearings, contributing to the efficiency and reliability of engineering systems. The study not only highlights the material’s potential but also opens opportunities for advanced, self-lubricating bearing materials, emphasizing the importance of material design in advancing engineering technologies.
