Kinetics of subsurface hydrogen adsorbed on niobium: Thermal desorption studies
The adsorption/absorption of hydrogen and the adsorption of carbon monoxide by niobium foils, at room temperature, was studied using thermal desorption spectroscopy. Two hydrogen desorption peaks were observed with a maximum at 404 and 471 K. The first hydrogen desorption peak is regarded as hydrogen desorbing from surface sites while the second peak, which represents desorption from surface si...
متن کاملThermal Desorption Spectroscopy of Hydrogen from Amorphous Hydrogenated Silicon
T h e r m a l desorption spectroscopy (TDS) based on the mass spectroscopy of thermal ly evolved hydrogen is used for desorption analysis of amorphous hydrogenated silicon (a-Si:H). Two series of glow discharge chemical vapour deposited a-Si:H were investigated by the T D S method . Cons tan t t e m p e r a t u r e growth ra te enabled to determine t empera tu re regions of hydrogen evolution a...
متن کاملThermal Desorption of Hydrogen at the Titanium Hydride-Oxide Interface
Changes in hydrogen distribution in -phase titanium hydrides (TiH1:92 1:95), covered with titanium oxide layers (TiO and TiO2), were investigated by elastic recoil detection analysis (ERDA) after isochronal and isothermal annealing experiments. The hydrogen concentration near to the surface of the hydride exponentially decreased as a function of annealing time in the temperature range from 423 ...
متن کاملThermal Desorption Analysis of Hydrogen in Non-hydrogen-Charged Rolling Contact Fatigue- Tested 100Cr6 steel
Hydrogen diffusion during rolling contact fatigue (RCF) is considered a potential root cause or accelerator of white etching cracks (WECs) in wind turbine gearbox bearing steels. Hydrogen entry into the bearing steel during operation is thought to occur either through the contact surface itself, or through cracks that breach the contact surface, in both cases by the decomposition of lubricant t...
