The corrosion initiation processes of the proven damages due to pitting and uniform corrosion will be analyzed by a combination of the electrochemical noise and acoustic emission method. By using different test methods an early damage detection technique will be developed. Running outdoor exposure tests are continued and the results will be correlated to the laboratory tests. A further objective is the investigation of the influence of increased pressure and temperature on the corrosion kinetic, with the aim to develop a damage model under extreme climatic conditions.

将电化学噪声和声发射方法相结合，分析点蚀和均匀腐蚀引起的已证实损伤的腐蚀起始过程。通过使用不同的测试方法，将开发早期损伤检测技术。继续进行室外暴露测试，并将结果与实验室测试相关联。另一个目的是调查增加的压力和温度对腐蚀动力学的影响，目的是开发极端气候条件下的损坏模型。
