Surface adsorption hydrogen rapid detection method of high-strength steel hydrogen damages

The invention provides a surface adsorption hydrogen rapid detection method of high-strength steel hydrogen damages. The surface adsorption hydrogen rapid detection method comprises the following steps: measuring a low-frequency end inductive impedance arc in an acid corrosion medium of high-strength steel by using an electrochemical impedance spectrum testing method; fitting an equivalent circuit by using impedance to fit the low-frequency end inductive impedance arc so as to obtain the resistance size of an inductance resistor for representing the adsorption capability of hydrogen ions on a metal surface; and judging the hydrogen damage degree of the high-strength steel by using a measured numerical value of the inductance resistor according to a relation of the adsorption hydrogen inductance resistor, a hydrogen permeation amount and the hydrogen damages. According to the surface adsorption hydrogen rapid detection method, the adsorption capability of hydrogen on the surface of the high-strength steel is detected so as to evaluate the permeation behavior of hydrogen atoms into the high-strength steel, and furthermore, the effect of detecting the damage degree of the mechanical property of the high-strength steel by the hydrogen permeation atoms is realized. The invention provides a detection technology for rapidly and losslessly evaluating the hydrogen damages of materials in situ, and is applicable to engineering application.
