This paper looks at the measurement of both profile and roughness on metal surfaces prepared specifically to receive a coating system in order to protect it from corrosion. The difference between roughness and profile is discussed, whether one is more relevant than the other, and the merits of the different measurement methods for both parameters.
This paper will evaluate methods used to measure surface profiles created by power tools, namely air needle scalers, bristle cleaners, and roto peen scalers. Particular focus will be placed on the use of replica tape and its ability to characterize profiles of various surfaces using a digital replica tape reader with 3D imaging capability. More specifically, this paper will determine if the measurement methods described in ASTM D44171are appropriate for the measurement of profiles produced by power tools.

Many coating product data sheets call for surface profiles of 3-4 mils. Others call for 1.5-2 miles surface profile for a very similar coating type – why should this be? To start to understand this we need to first of all look at why we measure the surface profile on steel surfaces. It pretty much comes down to two main things.
Coating performance is related to the profile height on a steel surface. Three types of devices are available to take measurements of this surface profile: replica tape, depth micrometers fitted with pointed probes, and stylus roughness testers. This paper presents results from a recent analysis of measurements taken by the three device types on steel blasted with an assortment of blast media and proposes a new method of depth micrometer measurement called average of the maximum peaks.
