MAX相/MXene增强Ag基电触头材料研究现状与展望
Research Status and Prospects of MAX Phase/MXene Reinforced Ag-Based Electrical Contact Materials
摘要
Abstract
As the core supporting material in low-voltage switches,the performance of Ag-based electrical contacts directly influences the safety and reliability of power system operations.The application of traditional Ag/CdO is limited due to the toxicity of Cd,while existing non-toxic alternatives suffer from significant deficiencies in both microstructure and performance.MAX phase,along with their two-dimensional derivatives,MXene,combine the advantages of both metals and ceramics,showcasing distinctive characteristics in processing,electrical and thermal conductivity,and arc erosion resistance.They are therefore promising candidates as environmentally friendly reinforcement phases for Ag-based contacts.This review firstly provides a comprehensive overview of the types,development,and advantages and limitations of traditional Ag-based electrical contact materials.It further summarizes recent research advancements in the fabrication processes,composition selection,microstructural regulation,and performance optimization of Ag/MAX/MXene composites.Special emphasis is placed on the arc erosion resistance and the underlying mechanisms of Ag/MAX/MXene composites.Finally,based on the evaluation of the application potential of this composite system in electrical contacts,the current challenges and future development directions are discussed.关键词
