The utility model discloses a
nickel bottom multi-plating electroplated
coating, a terminal and an
electronic interface, comprising an electroplated base material, the top of the electroplated base material is fixedly provided with a
nickel metal layer, the thickness of the
nickel metal layer can be 1-4 microns, the top of the nickel
metal layer is fixedly provided with a nickel
tungsten layer, the top of the nickel
tungsten layer is fixedly provided with a nickel
phosphorus layer, and the nickel
phosphorus layer is fixedly provided with a nickel
phosphorus layer. And the thickness of the nickel-
tungsten layer and the nickel-phosphorus layer can be 0.5-5 microns. According to the nickel-bottom multi-plating
electroplating coating, the terminal and the
electronic interface, in the daily use process, the nickel metal layer is electroplated on the surface of the
electroplating base material, the thickness of the nickel metal layer is preferably 1-4 microns, the flatness of the base material can be adjusted, and the nickel metal layer has good
adhesive force with the
electroplating base material; the
corrosion resistance, the
oxidation resistance and the flatness of the terminal can be improved, and the high
temperature resistance and the
wear resistance of the terminal are enhanced.
