Abstract
In response to the claim of environmental protection, silver paste sintering emerges to be an alternative to traditional electroplating to prepare silver coatings on electrical components. The sintering process is straightforward, low-cost, and typically carried out in a furnace, making it more suitable for mass production compared to magnetron sputtering. In this work, silver coatings were fabricated on copper slip rings which are widely used for sliding electrical conduction. By investigating the morphologies, bonding strength and contact resistance, we found that the as-prepared silver coatings own satisfying mechanical and electrical properties, e.g., enhanced wear resistance, low contact resistance and resistance fluctuation. The influence of sintering time and temperatures on coating porosity and electrical performance was also elucidated.
期刊介绍：
ASM International''s Journal of Materials Engineering and Performance focuses on solving day-to-day engineering challenges, particularly those involving components for larger systems. The journal presents a clear understanding of relationships between materials selection, processing, applications and performance.
The Journal of Materials Engineering covers all aspects of materials selection, design, processing, characterization and evaluation, including how to improve materials properties through processes and process control of casting, forming, heat treating, surface modification and coating, and fabrication.
Testing and characterization (including mechanical and physical tests, NDE, metallography, failure analysis, corrosion resistance, chemical analysis, surface characterization, and microanalysis of surfaces, features and fractures), and industrial performance measurement are also covered
