华盛顿州威司登豪斯·汉福特公司研制了一种用于含氚等氢同位素的先进核系统的金属涂层。该公司声称,山于使用了铝化镍表面涂层,氢渗透阻力层减少了氢同位素通过常用金属管路的扩散速度。虽然铝化镍已经用于喷气发动机涡轮叶片,但这种涂层扩大了该工艺的新用途。由发明人J·C·麦盖和W·F·布雷恩指导的研究工作表明,为奥氏体不锈钢和其他合金所研究的工艺可以用于产生氘的液态金属冷却反应堆系统以及裂变能系统。铝化镍可与用于反应堆系统的熔融钠 Westenhaus Hunt, Washington, has developed a metal coating for advanced nuclear systems containing hydrogen isotopes such as tritium. The company claims that Yamauchi has used a nickel-aluminide surface coating that reduces hydrogen diffusion through conventional metal lines. Although nickel aluminide has been used in jet engine turbine blades, this coating expands the new use of the process. Research conducted by inventors JC McGraw and WL Bryan shows that the processes studied for austenitic stainless steels and other alloys can be used for deuterium-producing liquid metal cooled reactor systems and fission energy systems. Nickel aluminide is compatible with molten sodium used in reactor systems
