摘要
This paper presents results obtained from a long-term water-line corrosion experiment using a wire beam electrode. The instantaneous rates of water-line corrosion of steel (UNS no. G10350) were regularly measured over an exposure period of 404 days. Based on these instantaneous corrosion rate data, corrosion depths were calculated at various stages of the corrosion exposure period, and these were summed up to produce an accumulated corrosion depth map. This accumulated corrosion depth map was found to be quantitatively comparable with a microscopically observed corrosion depth map. (C) 2001 Elsevier Science Ltd, All rights reserved.
