Over the past few years there has been a continuing study of the effects of various sorts of manufacturing processes on the texture of engineering surfaces. It has been shown that surface profiles contain a history of the processes used to create them, and that the history is revealed when the cumulative distributions of the height of the surface profiles are plotted on normal probability co‐ordinates. These plots reveal various strata within the profiles which may be related to the creation processes and, in many cases, the parameters of the processes may be determined. Earlier work has considered two‐strata surfaces created by processes which either add material to the peaks or to the valleys of a surface profile or remove material from them, and three‐strata surfaces created by processes which displace material within a profile. The present work considers the three‐strata surfaces which are created by material addition or removal processes such as plating and etching which act on the surface profile as a whole. It thus completes the classification scheme for surface profiles which was originally outlined at the beginning of these efforts. The analytical technique described in this work and the earlier work on this subject are the surface metrologist's analogs to the techniques used by geologists and archeologists. They also determine history by an examination of the strata evidenced by the surfaces which they study.
