Device and method for simulating deep-sea hydrogen charging

Abstract

The invention provides a device and a method for simulating deep-sea hydrogen charging. The device comprises a hydrogen charging tank, a sealing cover, a sample electrode, a platinum electrode and a liquid / gas inlet, the hydrogen charging tank and the sealing cover are sealed through conical surface matching and fastened through a stud and a nut, and gaskets are arranged between the nut and the hydrogen charging tank as well as the sealing cover; the sample electrode and the platinum electrode tightly jack a lugged sleeve through cooperation of a porous jacking bolt and the sealing cover. Theinsulating lugged sleeve solves the problem of sealing of the device and the problem of insulation of the device during electrochemical hydrogen charging; pressurizing of simulation environment can berealized through the liquid / gas inlet. By the device and the method, hydrogen charging behaviors of materials in deep-sea environment and study of hydrogen-induced cracking performance can be realized.

Description

Technical field: [0001] The invention relates to the field of hydrogen charging behavior in deep sea hydrostatic pressure environment, in particular to a device and method for simulating deep sea hydrogen charging. Background technique: [0002] With the development of production and life in human society, human demand for resources is increasing. The reserve of terrestrial resources can no longer meet the needs of human beings, which forces human beings to turn their attention to the ocean. The ocean area accounts for about 71% of the earth's surface area, and there are a lot of resources in the seabed, such as: oil, natural gas, combustible ice, manganese nodules, etc. However, in order to develop and utilize deep-sea resources, it is necessary to rely on relevant deep-sea equipment, which requires the development of metal materials suitable for deep-sea environments. The biggest feature of the deep sea environment is its high hydrostatic pressure. Qu Shaopeng and others...

AI Technical Summary

Problems solved by technology

The first method has a longer experimental cycle and lower efficiency, and due to the direct use of toxic gas H 2 S conducts experiments, so it has higher requirements on laboratory conditions; the second method is more efficient and has relatively loose requirements on laboratory conditions

At present, the research on hydrogen charging of metal materials by electrochemical methods is limited to normal temperature and pressure conditions, and there are few experimental devices suitable for simulating hydrogen charging under deep sea high hydrostatic pressure conditions.
