The Effects of Environmental Factors on the Pitting Corrosion of 304 Stainless Steel

摘要：

The effects of environmental factors, such as pH and buffer capacity, on the pitting break potential (Ebreak) and protect potential (Eprotect) of type 304 stainless steel was investigated by cyclic voltammetry sweeps method. The buffer capacity and the concentration of non-aggressive anions in the solutions indicate some effects on the pitting initiation and repassivation of stainless steel. Nevertheless, the pitting Ebreak and Eprotect show a strong dependence on a parameter J as general environmental factor, which is defined as the product of concentration of aggressive anions and buffer capacity. Study pitting Ebreak and Eprect of 304 stainless steel by environmental factor suggested a new method to investigate the anti-corrosion ability of iron base metal.
