Description

technical field

[0001] The present invention relates to a high-temperature and high-pressure fluid environment loaded tensile stress sample corrosion electrochemical experiment device and test method, more specifically, it relates to the electrochemical test of the corrosion process of metal materials in the high-temperature and high-pressure liquid fluid environment that is simulated when the tensile stress is loaded A device, and a method for using the device to perform in-situ electrochemical real-time online testing. Background technique

[0002] In industries such as petroleum industry, chemical industry and electric power industry, the environmental conditions in many production links are very harsh, and metal equipment and parts are widely faced with high temperature and high pressure liquid phase fluid environment. In such environments, metals are subject to severe corrosion. In the corrosion process, there are not only the erosion of the corrosive medium, but also ...
