使用电化学动电位再活化法研究热处理工艺对304不锈钢晶间腐蚀敏感性的影响
Influence of Heat Treatment Process on the Intergranular Corrosion Susceptibility of 304 Stainless Steel Evaluated by Electrochemical Potentiodynamic Reactivation Method
摘 要
采用电化学动电位再活化（EPR）法研究了不同加热温度、保温时间和冷却方式热处理后的304不锈钢的晶间腐蚀敏感性。结果表明：EPR 法可定量评价304不锈钢的晶间腐蚀敏感性；304不锈钢在500～800 ℃热处理会发生敏化，在650 ℃左右敏化度最高；304不锈钢在650 ℃以上热处理时，快速冷却能够有效地降低其晶间腐蚀敏化度，若采用炉冷则会提高其晶间腐蚀敏化度。

Abstract
Electrochemical potentiodynamic reactivation (EPR) method was used to study the intergranular corrosion susceptibility of the 304 stainless steel under different heating temperature, holding time and cooling mode. The results show that:the EPR method could quantitatively evaluate the intergranular corrosion susceptibility of the 304 stainless steel; the sensitization would happen to the 304 stainless steel when the heat treatment temperature was 500-800℃, and the sensitization degree was highest at approximately 650℃; when the 304 stainless steel was heat treated at the temperature of above 650℃, rapid cooling could effectively reduce the sensitization degree of intergranular corrosion, but furnace cooling would increase its sensitization degree.
