In this laboratory work, zero resistance ammeter measurements were used to collect galvanic corrosion measurements for scribed organic coating samples and e-coated samples in situ. For this work, a new sample design was derived from samples currently used in the automotive industry consisting of a base plate and a cover plate of another material to form a galvanic couple with a crevice between them. The samples were connected to a developmental test system that uses zero resistance ammeter (ZRA) measurements to collect galvanic corrosion rates for multiple samples in situ. E-coated samples were evaluated in accelerated corrosion tests for comparison with traditional organic coatings. A description of the samples, electrochemical measurement device, and methods for coating testing will be reported along with the analysis of the resulting data and its implications for evaluating various coating types.
