Description

technical field [0001] The invention belongs to the field of measuring instruments, relates to the corrosion performance test of materials in deep sea environment, and provides a corrosion performance test device for materials simulated by factors such as medium and pressure in deep sea environment. Background technique [0002] The utilization of deep-sea technology is inseparable from the use of various materials and equipment in the deep-sea environment, and materials and equipment will inevitably encounter various corrosion problems in the deep-sea environment. In the 1960s, advanced countries such as the United States began the research on the corrosion test of materials in deep sea environments. Over the past two decades, countries such as Norway, the United Kingdom, Russia, and India have also actively carried out related research work to provide information on the corrosion behavior of materials in deep sea environments. Some research results have been accumulated. ...
