Hydrogen in Amorphous Metals—i

Abstract: The solubility and diffusivity of hydrogen in amorphous Pd 77 5 Cu 6 Si 16>5 and Ni 4 9.9Pd 31 8 P Î 8 3 have been measured using an electrochemical method. The pressure-concentration isotherms show remarkable deviations from Sievert's Law while the amount of hydrogen dissolved lies in between the solubility of the components of the alloy. The diffusivity of hydrogen is rather high (about 10~8 cm 2 /s) and it depends on temperature and also on concentration even at very low hydrogen levels contrary to crystall… Show more

“…Therefore, it is assumed that the hydrogen diffused through wear-induced nascent surfaces. A technique by KircTech GmbH for online or offline measurement for hydrogen diffusing into steel during RCF has recently been reported 18 which involves spot welding a probe to the steel that collects hydrogen and resolves concentration, either on the non-contact side of static raceways (for online monitoring) or rotating components (for offline pre- vs. post-measurements). It has been shown in FAG-FE8 thrust washer configurations that the sensor is able to detect hydrogen diffusion with certain oils known to promote WSF occurrence versus oils that do not.…”

“…The crystallized membrane isotherms show sorption curves with a shape different from that of the amorphous sample: the crystallized sample displays the presence of a "slopey" pressure plateau, as, indeed, expected for crystalline compounds [23]. Additionally, the crystalline membranes show a hysteresis between absorption and desorption.…”
