We have demonstrated the reduction of tritium gas permeation through 304L stainless steel using aluminum ion implantation. The implanted aluminum was selectively oxidized to form a thin, coherent, and stable Al/sub 2/O/sub 3/-rich layer on the stainless-steel surface. Tritium permeability at 100 and 170 /sup 0/C was reduced 600--700-fold compared to clean stainless steel and 20-fold compared to stainless steel with native oxide. Since greater reductions are expected with improved Al/sub 2/O/sub 3/ layers, this approach is a promising alternative for reduction of permeation of all hydrogen isotopes through stainless steel and other materials.
