Abstract

Disc Sickle; Acoustic Emission evaluation; pitting corrosion damage Abstract. By the pitting corrosion simulation test in the laboratory, the law that the Disc Sickle corrosion degree and AE signal vary with corrosion time has been studied, and relationship curve between corrosion damage and AE parameter has been obtained. This explains that AE technology can be used for detecting forepart pitting corrosion, researching the law of pitting corrosion development, and evaluating corrosion damage.
