abstract = {Ag/MAX electrical contacts show great potential for low-voltage switching applications. However, the influence of MAX phase structural characteristics on interfacial diffusion, material transfer behavior, and nanomechanical evolution of Ag/MAX composites under arc erosion remains unclear. In this study, Ag/Ti3AlC2 and Ag/Ti2SnC composites were fabricated, and their interfacial evolution, material transfer behavior, and nanomechanical degradation during arc erosion were systematically investigated. The results reveal that the structural differences between Ti3AlC2 and Ti2SnC significantly affect the arc-induced degradation behavior of Ag/MAX composites. Due to the weaker Ti-Sn bonding, Ti2SnC exhibits higher interfacial reactivity at elevated temperatures, promoting Sn diffusion into the Ag matrix and enhancing interfacial bonding, thereby suppressing molten Ag migration and reducing material loss. In contrast, Ti3AlC2 with stronger Ti-Al bonding maintains higher structural stability during arc erosion, resulting in less structural decomposition and superior nanomechanical retention after erosion. This work establishes the relationship between MAX phase bonding characteristics, arc-induced interfacial diffusion, material transfer behavior, and nanomechanical evolution, providing insights into the design and optimization of high-performance Ag/MAX electrical contact materials.}
