Accelerated Dynamic Corrosion Test Method Development

Abstract

Perhaps the most widely recognized accelerated corrosion test is the ASTM B117 salt fog test. However, numerous studies have demonstrated that this test method has poor correlation to outdoor exposures, particularly for non-chromate primers. As a result, more realistic cyclic environmental exposures have been developed to more closely resemble actual atmospheric corrosion damage. Several existing tests correlate well with the outdoor performance of some materials and assemblies of interest, but not all. The risk, then, is that promising new environmentally friendly technologies may be incorrectly rejected based on corrosion processes observed in flawed laboratory tests.
