Abstract

The invention discloses an in-situ hydrogen display detection device and a detection method. The in-situ hydrogen display detection device comprises a first box body, a second box body, a galvanostatand a heating mechanism, a box cover is arranged at the top of the first box body, a first air inlet and a first air outlet are formed in the box cover, a first opening is formed in the bottom of thefirst box body, and a metal platinum sheet is arranged in the first box body; the second box body is arranged at the bottom of the first box body and is detachably connected with the first box body, the bottom of the second box body is provided with a liquid inlet and a second air outlet, the top of the second box body is provided with a second end opening opposite to the first opening, and the opening edge of the second end opening and the opening edge of the first opening are arranged in a spaced mode; the positive electrode of the galvanostat is electrically connected with the metal platinum sheet, and the negative electrode of the galvanostat is used for being connected with metal to be detected; the heating mechanism is used for providing heat for the second box body. According to themethod, different metals can be subjected to electrochemical hydrogen charging, so that the influence of microdefects in the metals on hydrogen capture can be conveniently detected in situ.

Description

technical field [0001] The invention relates to the technical field of electrochemical experiments, in particular to an in-situ hydrogen display detection device and a detection method. Background technique [0002] When metal materials, especially steel materials, serve in acidic environments, hydrogen enters the steel matrix due to the interaction between materials and hydrogen. The hydrogen atoms entering the material will be trapped and enriched in the microstructure defects of the material. The presence of hydrogen will reduce the mechanical properties of the material, and even cause hydrogen-induced cracking (HIC), leading to material failure. Exploring the influence law and mechanism of metal microstructure defects on hydrogen capture will help improve the safety of materials in service and reduce economic losses. [0003] A common method to study the effect of hydrogen on metal materials is to simulate the interaction between hydrogen and materials, explore the fact...
