Research on Electroplating Nickel-phosphorus Alloy on Different Coatings
When the rare earth NdFeB permanent magnet material is electroplated on the surface of the nickel-phosphorus alloy coating,it is necessary to pre-plating a layer of nickel-phosphorus alloy on the surface of the rare earth NdFeB permanent magnet material before the electroplating of the nickel-phosphorus alloy can be continued;The effects of different pre-plating layers on the surface appearance and properties of nickel-phosphorus alloys were studied by comparing the gloss,roughness,plating speed,100 grids,microstructure,magnetic decay and salt spray resistance of the coatings on different substrates of nickel-phosphorus alloys.Experiments show that the upper plating of nickel plating is better than that of copper plating,and the multi-layer plating is better than that of single coating.
