This project sought to validate the concept that there is a relationship between the mechanical performance of an organic coating on steel products and its dielectric properties, and hence its corrosion performance. A large effort was concentrated on identifying and calibrating the forming processes and the performance testing procedures necessary to undertake the project. The method by which the coated steel can be strained to give a significant range of strain levels has been investigated. Also, an electrochemical method of measuring the effect of forming on the dielectric properties of the organic coating has been developed. A study to determine the extent to which ageing an organic coated steel affects its formability has also been studied. The findings from these studies indicate a measurable relationship between the mechanical properties of an organic coating and its dielectric properties (corrosion performance). In general, the performance of the organic coating is reduced with an increasing degree of forming. The findings also indicate that the formability of an organic coating is reduced when the coating undergoes a weathering cycle before it is formed.
