Abstract

A method that provides a numerical assessment of the quality of electroplates is described. The procedure using the Taylor-Hobson Talysurf machine is equally suitable for the examination of small areas of a surface or for providing an average assessment in terms of roughness of the overall area. The method has been applied to the examination of specimens of mild-steel electrodes electroplated with aluminium. Some of the specimens, visually indistinguishable from one another in quality, were easily given a numerical assessment by the 'centre line average' values provided by the machine. The procedure is easier, is non-destructive and less time-consuming than photomicrography, in which a large number of sections must be examined to obtained an overall assessment of the surface finish. © 1973.
