Most of the performance assessment in the automotive electrocoat industry relies on continuous salt spray exposure tests or cyclic tests, which typically consist of a combination of salt spray and cycles of humidity and temperature. Because the analysis of the results is usually limited to visual quantification of corrosion, these tests alone offer little information about the mechanisms of coating degradation and their rate of progression. In this work, electrochemical tests were employed in tandem with accelerated exposure tests to better understand the degradation mechanisms of electrocoated steel. Different electrocoats were ranked based on their performance in cyclic cabinet tests, full immersion in NaCl, or by accelerated electrochemical methods. Finally, the trends observed in corrosion behavior were compared, and conclusions were drawn based on the mechanisms captured by electrochemical techniques and their relevance in each testing protocol.
