摘要

After several years of research in laboratory, the ability to detect active corrosion by AcousticEmission technique has been successfully proved. The benefit of using this technology hasbeen recognised by chemical and petrochemical industry to detect stress corrosion crackingand pitting of stainless steel alloy.The purpose of this paper is to present an extension of this technique to coated low alloycarbon steel. In this case, the mechanism of corrosion is well-known uniform corrosion butthe damage appears in restricted area where the passive protection is no more efficient. Thegoal is to make a diagnosis on the propagation of the localised corrosion or to verify theintegrity of the corrosion protective layer on components during in service conditions.This need arises from unpredicted failures of industrial equipments due to fast propagation ofcorrosion damage, after the destruction of coating.This paper presents several situations where CORPAC? technology has been applied, notonly to detect and locate damage from corrosion, but also to validate repairs and evaluate theefficiency of corrosion protection.
