Abstract

Highlights: The phenomenology and mechanisms of crevice corrosion are explained. Techniques for evaluating crevice corrosion and their limitations are discussed. Effects of alloy composition, environment factors and dissolved O2 are presented. Future development axes for studying crevice corrosion are proposed. Abstract: Crevice corrosion is a localized accelerated dissolution of metal that occurs as a result of a breakdown of the protective passive film on the metal surface. This work provides an overview from the literature of the most important techniques used for evaluating crevice corrosion and the critical factors influencing the crevice corrosion of stainless steels with emphasis to oil and gas industry. The phenomenology and mechanisms of crevice corrosion are discussed, including the effects of the alloy composition, environment, temperature, and dissolved oxygen on the corrosion behavior. Future development axes for studying crevice corrosion are proposed.
