[0002] With the development of China's economy and the progress of industrial level, the development and utilization of the ocean are becoming increasingly extensive. In the process of developing and utilizing the ocean, various materials are indispensable. Seawater is a strong corrosive electrolyte, and the ocean environment covers many factors such as temperature, humidity, sea salt, and wave impact. All kinds of ocean engineering materials used in the ocean environment are constantly tested by complex and harsh environments.

[0003] Therefore, before the ocean engineering materials are officially put into use, it is necessary to test the performance of the ocean engineering materials. Due to the regionality, complexity, and economic problems of the ocean environment, a large amount of manpower and material resources are wasted in the tests, and the research on simulating the ocean environment has emerged as the times require.

Although the static salt spray corrosion test ensures the reproducibility of the test results, it still has the disadvantages of unsatisfactory accelerated corrosion effect, long detection period, and low correlation with actual working conditions; although the electrochemical corrosion test has a short test time, the application environment is very different from the actual working conditions, and it is only an auxiliary test method. In the face of the increasing detection requirements for ocean engineering materials, it is extremely urgent to develop a new detection device with good correlation and obvious acceleration, namely a test chamber for simulating ocean waves.
