Abstract

Hydrogen diffuses quickly in metals, making them brittle and accelerating crack propagation. Controlling the mobility of hydrogen in metals is one of the key factors used to prevent hydrogen embrittlement. If the hydrogen diffusion, i.e., mobility, at the surface can be suppressed, the resistance to hydrogen embrittlement will be greater. The diffusion in austenitic stainless steel can be suppressed by introducing a compressive stress near the surface and that the hydrogen diffusion coefficient is thereby reduced to one-tenth from 1.13×10-15 s/mm2 to 1.23×10-16 s/mm2, obtained by SIMS.
