Experimental DC polarisation curves are the sum of the cathodic and anodic components and can be difficult to interpret. Schematic representations of 'typical' curves (together with their anodic and cathodic components) are available in the literature for comparison purposes. A better approach to curve analysis is to generate mathematically the experimental curve which is then deconstructed into its components. Unfortunately the appropriate computer programmes are not readily available. We have considered it useful to revisit the collected curve concept replacing schematic representations with experimental curves. Using an updated programme we have accurately analysed curves representative of the Fe/H2O/H+/O-2 corrosion system. (C) 2004 Elsevier Ltd. All rights reserved.
