ActiveCorrosion of metals and alloys - Electrochemical potentiokinetic reactivation measurement using the double loop method
金属和合金的腐蚀 双环电化学动电位再活化测量方法
Application Summary AI generated
This standard specifies the double loop electrochemical potentiokinetic reactivation (DL-EPR) method for evaluating the susceptibility of stainless steels and nickel-based alloys to intergranular corrosion. It is applied in metallurgical testing and quality control to quantify the degree of sensitization in materials, particularly after welding or heat treatment. The method is used by laboratories and industries such as chemical processing, power generation, and aerospace to ensure material reliability in corrosive environments.
