Latest Patents

One of Chen's latest patents is a preparation method of electrical contact material. This method involves adopting chemical plating to cover nickel coating on aquadag or metallic oxide, followed by a silver coating. The resulting Ag—Ni—C or Ag—Ni—MeO core-shell structure significantly improves the interface wettability of the materials, addressing the mechanical property issues associated with conventional powder metallurgy methods. Notably, this innovation reduces the silver usage by replacing it with nickel coating, while still enhancing the inoxidizability and deformability of the composite particles during manufacturing.

Another significant patent is the method of preparing silver-based oxide electrical contact materials with a fiber-like arrangement. This process includes several steps, such as mixing silver-metal alloy powders with graphite, ball-milling, and cold-isostatic pressing. The resulting materials exhibit improved resistance to welding and arc erosion, conductivity, and overall processing performance. The simplicity of this method makes it accessible and efficient for production.
