Description

Technical Field

[0001] The invention relates to an integrated hydrogen permeation detection device, which is particularly applicable to detecting hydrogen permeation in electrodeposition, brush plating, alternating electrodeposition and brush plating processes and hydrogen charging processes. Background Art

[0002] As one of the core mechanisms of material failure, hydrogen embrittlement poses a risk throughout the entire material life cycle, encompassing both manufacturing and service applications. Reducing the hazards of hydrogen embrittlement has always been a major concern. Electrodeposition technology plays an irreplaceable and important role in the field of surface processing because it can deposit complex samples, has significant economic benefits, and is simple and easy to mass-produce. However, since most electrodepositions rely on aqueous solutions as the deposition environment and ion source, water dissociation reactions (H2O→H + +OH - ) and hydrogen evolution reaction (H + +e - →H), some of the generated active hydrogen atoms recombine to form hydrogen molecules and escape, while others diffuse into the substrate. This hydrogen permeation behavior causes lattice distortion and stress concentration at the microscale, and at the macroscale, it leads to embrittlement and delayed fracture of the coating. To address this problem, precise monitoring of changes in hydrogen evolution during surface modification can be used to adjust process parameters in a timely manner, effectively reducing the probability of hydrogen embrittlement and improving the stability and reliability of the coating. Current research primarily uses a dual-electrolytic cell system, as described in the paper "Hydrogen Permeation Behavior and Corrosion Resistance of Zn-Ni Alloy Electrodeposition," to achieve dynamic monitoring of hydrogen permeation.

[0003] In the field of modern surface engineering, brush plating has become a key branch of electrodeposition technology due to its unique non-immersion operation mode. Conventional electrodeposition achieves global electrochemical deposition by immersing the entire workpiece in an electrolyte system; brush plating uses a plating pen to dynamically apply electrolyte to achieve localized, targeted deposition. The former exhibits excellent coating uniformity and deposition efficiency, significantly improving the material's corrosion resistance and wear resistance. The latter, by virtue of its ability to precisely control the coating composition and structure, imparts unique physical and chemical properties to the material. The combination of the two can achieve multiple performance optimization combinations on the same workpiece, meeting the stringent material performance requirements of complex working conditions. However, due to differences in process principles and equipment configurations, traditional electrodeposition and brush plating have long been used independently, making it difficult to achieve complementary process advantages. Furthermore, this composite process experiences a cumulative effect of hydrogen permeation during dynamic switching, and no detection technology has yet developed a hydrogen permeation monitoring device suitable for alternating deposition conditions. Consequently, process parameter optimization lacks a quantitative evaluation basis for hydrogen-induced damage. Summary of the Invention

[0010] It is difficult for the prior art to flexibly carry out various surface treatment processes under closed conditions. The present invention enables the substrate to perform electroplating, brush plating, and their alternating operations under closed conditions, and to detect the hydrogen permeation amount.
