Tohoku University Technology: Eye-readable hydrogen detection system for metals: T21-064
On field visual detection of hydrogen permeation into metallic material
In order to prevent hydrogen embrittlement in which hydrogen penetrates into a material and degrades its mechanical property such as strength, it is effective to visualize distribution of hydrogen penetrated into the material. Silver decoration method and hydrogen microprint technique are known as conventional hydrogen observation methods, but these methods are not able to detect the time variation of the hydrogen distribution in real-time. In the past, Tohoku University made the real-time detection possible by using metallic oxide, but the sensitivity was low and could not detect the small amount of hydrogen atoms that migrate into the material due to corrosion. This system is able to detect the hydrogen in real time with high sensitivity and high spatial resolution in an actual environment. This technology is effective for example to visually judge hydrogen permeation into plant equipment.
