Surface roughness is an important factor that affects the function of the workpiece.Cutting down the workpiece's surface roughness degree can improve the mechanical function of the workpiece's surface. In order to master the regularity of the workpiece's surface roughness which is plated,in the same kind of the Ni-P plate liquid,we plate the same thickness to the workpieces which have the different surface roughness.By contrasting the data,we find the surface roughness decreased after plating.By analyzing the microcomic shape of the electroless plating's surface,we find the reason of the surface roughness decreasing is that the sediment area of the wave through and wave crest is changed.After calculating,so we can conclude that the higher the original workpiece's surface roughness degree is,the more that reduction is.The range of the reduction is about 11 percent of the original workpiece's surface roughness degree.
