Laboratory Investigations into the Edge Corrosion Protection Capacity of Organic Coatings

From JPCL, May 2012

More items for Quality Control

by Sascha Buchbach, Dr. Peter Plagemann, Fraunhofer Institute for Manufacturing Technology and Applied Materials Research; and Dr. Andreas W. Momber, Muehlhan AG

This article begins with a summary of the first part of a research study on how edge geometry and coating type affect the corrosion performance of organic coatings on edges, with particular attention to ballast seawater tank applications. The article then reports test results from the second part of the study, which concentrated on the effects of various treatment methods and tools on the performance of coatings on edges in ballast tanks....

1. The statistical analysis that edge radius is not important seems flawed as only two radii 1mm and 2mm are considered. In order to claim there is no correlation, values of 0.1mm, 0.5mm and 3mm could have been used. It may be that a radius bigger than 1mm is all that is required. 2. Although the edge method is cited as important, the only information on this is a paper in German. When making such claims in English it would have seemed wise to include sample photographs of the edge condition in this paper. 3. Without such photos being provided it is difficult to assess whether the edges used for this study are representative of those used in any particular industry. If edges have micro features in the surface that have radii of less than 2mm then again the analysis would seem flawed, although this cannot be judged from the information provided. 4. It is not clear whether the heat effect on steel from the cutting processes described has increased the hardness of the edges, and so affecting the effectiveness of subsequent preparation methods, for the reasons stated above.

Ok. Talk to me like I'm 6, lol. Does this mean that stipe coating is an effective means of preventing edge corrosion - and that grinding or otherwise smoothing of edges is less important or not effective?
