Abstract
The hydrogen micro-print technique is one of ways to detect hydrogen which diffuse into several materials. By using this technique, we can indirectly observe a diffusible hydrogen with silver particles which is created from reduction of a silver bromide (AgBr) solution. Although, the repetition reproducibility of this technique have been not reported. In this study, the best procedures to obtain a reproducible analysis results have been investigated. For proofing this procedures, some materials - SUS316L for metallic materials and two types of plastic materials - that were exposed high pressure hydrogen were analyzed with a hydrogen micro-print technique.
