Abstract

In the computational evaluation of electrochemical corrosion systems painted surfaces are often treated as perfectly insulated. While many paint systems have a high resistance; the resistance is finite rather than infinite. In this work a range of finite resistivity values will be assigned to the painted surfaces in a boundary element model of a shipboard ICCP system. The studies performed were developed to provide an increased understanding of the effects of finite resistivity on system performance, provide a quantitative measure of the effects of ranges of finite paint resistivity on system performance and to increase the understanding of modeling methods to issues of damage and material polarization response definitions. 1 Introduction Corrosion damage is a major factor in sh
