Improving the wear and friction properties of racing sports automotive gears using SiC@Ag nanoparticles in lubricating oils

. In this study, the effects of Ag-doped silicon carbide nanoparticles on improving lubricating properties and reducing wear rates in racing automotive gears were investigated. At high temperatures and pressures, SiC@Ag nanoparticles enable the creation of a strong and durable lubricating layer by combining the lubricating properties of silver metal with the high hardness of silicon carbide. Using SiC@Ag nanoparticles until the optimal concentration is reached dramatically reduces the wear rate and friction coefficient, according to tests conducted on steel gears using nano-oils containing different concentrations of these nanoparticles under various loading and speed conditions. The formation of a thin, uniform lubricating layer with anti-stick properties was further confirmed by surface analysis of the samples. These findings demonstrate that adding SiC@Ag nanoparticles as a novel additive is an effective approach to enhance the efficiency and durability of power transmission systems in sports and automotive applications.
