Electrochemical test methods for evaluating organic coatings on metals: an update. Part I. Introduction and generalities regarding electrochemical testing of organic coatings

摘要: Abstract The status of evaluating organic coated metals utilizing electrochemical means was reviewed for the period 1988–1994. general improvements in overall technology are presented three sections. Part I covers test cell configurations, changes testing approaches and a brief survey measurement equipment. II presents methods involving single parameter such as panel potential relative to reference electrode, voltage and/or current noise, well dc resistance coating on metal substrate. Multiple measurements potentiodynamic curves impedance spectroscopy covered III. Although majority data were taken from literature, some supplementary included NSWCCD studies.
