Description

technical field [0001] The invention belongs to the technical field of marine engineering, and in particular relates to a deep-sea on-site corrosion electrochemical test device and a test method thereof. Background technique [0002] The marine environment is a harsh and corrosive environment. Metal structures such as port facilities, oil platforms, submarine pipelines, marine vessels, and deep submersibles must carefully consider the corrosion problems brought about by the marine environment during the design and use process. In order to grasp the corrosion behavior and law of various materials in the marine environment, and to provide the basis and basis for the design, material selection, protection and development of new materials for fixed or mobile marine steel structures, it is necessary to carry out corrosion tests in real sea environments and accumulate various The corrosion data of the material in the actual use environment. At present, standard test methods and t...
