Problems solved by technology

[0003] There are many methods for measuring hydrogen permeation of metal materials, such as pressure measurement method, high-pressure vacuum method, etc., but these methods require complicated equipment and low precision, so it is difficult to be popularized
At present, there is no standard instrument and equipment for the electrochemical method to measure the hydrogen diffusion performance of metals. If it is necessary to measure the hydrogen permeability of metals in scientific research and production, it is necessary to design and build the device by itself. The steps are cumbersome and increase the workload. , poor precision, low degree of automation, affecting the stability of the measurement results

Description

technical field [0001] The invention relates to the field of measuring the hydrogen permeability of metal samples by using electrochemical technology, in particular to a device and method for measuring the hydrogen permeability of metals Background technique [0002] The hydrogen permeation property is an important indicator of the properties of metal materials. Through the measurement of hydrogen permeation properties, the hydrogen storage properties of metal materials can be understood, so as to provide materials with matching properties for different application fields. For example, one of the requirements for the use of enamelled steel plates is that the steel plates have sufficient hydrogen storage capacity, so-called hydrogen traps, to prevent the enamel from scale explosion. Therefore, in the design and processing of metal materials, engineering design and process control, the hydrogen permeability test of metal materials is very important. [0003] There are many me...
