A method is proposed to attenuate hydrogen diffusion through fusion reactor components via controlled oxidation of prealloyed surfaces. Alloys of zirconium, vanadium, titanium, niobium, tantalum, tungsten, nickel and iron may be protected from hydrogen isotope permeation by using vanadium as an intermediate layer and either chromium, nickel-chromium, silicon or aluminum as the oxide forming component. This method may also be used to prevent hydrogen embrittlement of metals from external hydrogen environments and is applicable to the majority of alloy systems exhibiting hydrogen embrittlement phenomena. |
