Research on Corrosion Characteristics of Stainless Steel Bar in Stray Current and Chloride Ion Coexisted Environment

Abstract:

Based on the method of electricity migration, the characteristics of the stainless steel in concrete structure are researched on in stray current and chlorate coupling environment. Test results show that stray current could make the stainless steel in concrete structure corrosion in a short time; The corrosion feature of stainless steel is different from the common steel obviously on the surface, which shows uniform pitting corrosion mainly; In static current and constant voltage conditions, the corrosion time of concrete sample with stainless steel to crack is shorter than that with common steel; In static current and constant voltage conditions, the theoretical corrosion amount is well related to the actual one, but is higher than the measured value clearly.
