Published: — with international search report (Art. 2 I (3)) (54) Title: APPARATUS AND METHOD FOR THE NON-DESTRUCTIVE MEASUREMENT OF HYDROGEN DIFFUSIVITY Inner wall FIG. 2A (57) : A method of measuring a hydrogen diffusivity of a metal structure is provided. The method includes providing a hydrogen charging surface at a first location on an external surface of the structure, and a hydrogen oxidation surface at a second location adjacent to the first location on the external surface of the structure. A hydrogen flux is generated and directed into the metal surface at the charging surface. At least a portion of the hydrogen flux generated by the charging surface and diverted back toward the surface is detected, and a transient of the diverted hydrogen flux is measured. The hydrogen diffusivity of the metal structure is then determined based on the measured transient. 205
