In-situ hydrogen display detection device and detection method

Abstract

The invention discloses an in-situ hydrogen display detection device and a detection method. The in-situ hydrogen detection device includes a first box body, a second box body, a constant current meter and a heating mechanism. The top of the first box body is provided with a box cover, and the box cover is provided with a first air inlet and a first outlet Air port, the bottom of the first box has a first opening, the first box is provided with a metal platinum sheet; the second box is located at the bottom of the first box and is detachably connected with the first box, the second The bottom of the box has a liquid inlet and a second gas outlet, and the top of the second box has a second port opposite to the first opening, and the edge of the second port is connected to the edge of the first opening. The intervals are set at intervals; the positive pole of the galvanostat is electrically connected to the metal platinum sheet, and the negative pole of the galvanostat is used to connect with the metal to be detected; the heating mechanism is used to provide heat for the second box. The invention can perform electrochemical hydrogen charging on different metals, so as to facilitate in-situ detection of the influence of microscopic defects in metals on hydrogen capture.

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...
