Abstract

The invention discloses a temperature controllable electrolytic cell device simultaneously used for electrochemical experiments and slow strain rate tensile tests and a using method thereof. Accordingto the device, an electrolytic cell is formed in a reaction tank, and a circulating water tank is formed along the outer ring of the electrolytic cell, so that the temperature control of an experimental environment in the electrolytic cell is completed while a tensile test is carried out, and the fixing and sealing of a tensile sample are completed through the combination of a sealing plug, a sealing gasket and a rotary cover. The device can perform electrochemical tests, such as polarization curve measurement, electrochemical alternating current impedance spectrum, electrochemical noise tests and M-S curve measurement, on samples at different temperatures and under different stress conditions, and is used for analyzing the corrosion condition of the material.

Description

technical field [0001] The invention relates to an electrochemical test device, in particular to a temperature-controllable electrolytic cell device and a use method thereof which are simultaneously used for electrochemical experiments and slow strain rate tensile tests. Background technique [0002] Corrosion of metal refers to the deterioration and destruction caused by chemical or electrochemical interaction with the surrounding medium in the natural environment or under working conditions. With the gradual development of industry, the various industrial environments in which metals are located tend to be more complex, such as the water-hydrogen sulfide corrosion environment of oil transportation pipelines, the high-pressure chloride ion environment of deep-sea pipelines, the high-temperature and high-pressure environment of boiler pipes, etc. [0003] At present, common ways to slow down the corrosion rate of metals include sacrificial anode protection and impressed curr...
