Abstract

Silver (Ag)-matrix-composite electrical contact materials (ECMs) are widely used in railway, manufacturing, electric power distribution, and aerospace systems, owing to their excellent electrical and thermal conductivities and good mechanical and anti-erosion properties. In particular, they play a key role in low-voltage switches, which are vital in the global electrical economy. To date, substituting the toxic Ag/CdO ECMs has become a bottleneck in the development of low-voltage switches. Over the past decades, Ag/SnO2, Ag/ZnO, Ag/Ni, and Ag/C have been exploited as substitutes for Ag/CdO ECMs, but their intrinsic defects make them unsuitable; therefore, there is still an urgent need to develop eco-friendly substitutes for CdO. Recently, MAX-phase materials, which combine attractively dual metal and ceramic properties, have shown potential in replacing CdO as a reinforcement for Ag-matrix composites. Moreover, arc erosion is a common cause of the premature failure of low-voltage switches in applications. To aid the further development of MAX-reinforced Ag-matrix-composite contacts, there is a need to understand the mechanism of arc erosion and degradation of the microstructural and mechanical properties of the composites. Nano-indentation is the most common and stable method of evaluating the micromechanical properties of materials. In this study, micro-/nano-indentation tests were performed along the cross-section of Ag/Ti2SnC contacts (from the arc erosion layer to the near arc erosion layer and then to the matrix interior). The gradient variation of the microhardness, nanohardness, modulus, creep behavior, and plastic/elastic depth in different areas was analyzed and contrasted in the direction of the electrical arc erosion. The micromorphology and elemental composition were comprehensively analyzed, and the structural and compositional evolution of the Ti2SnC reinforcement phase and Ag matrix were investigated. The relationship between the gradient structural change and micro-/nano-mechanical properties of the Ag/Ti2SnC composites was analyzed. COMSOL simulations were employed to further demonstrate the physical characteristics of multi-field coupled erosion in the Ag/Ti2SnC composites; based on these analyses, we propose an erosion mechanism for the composites. This study not only provides insights into the intrinsic relationship between the structure and properties of Ag/MAX composites under arc erosion but also paves the way for the future design and development of eco-friendly contact materials for low-voltage switches.
