Influence of thin surface oxide films on hydrogen isotope release from ion-irradiated tungsten
We studied the influence of thin, electro-chemically grown tungsten (W) surface oxide films on hydrogen isotope release from W.As deuterium (D) reservoir underneath the oxide, we used a defect-rich, ion-irradiated W layer that was filled with D prior to oxidation.Several oxide films with thicknesses between 5 and 100 nm were studied and compared w
