Electrolytical charging with hydrogen has recently been found to inhibit the subsequent ion-irradiation-induced mixing of Fe, Co, Ni or Pd into Ti by factors of 7, 2.2, 2 and 1-1.5. It has been suggested that the effect depends on the stability of the hydrogen-vacancy complexes in these metals. An important consequence of this dependence would be that AlTi samples should behave like FeTi in this respect. In reasonable agreement with this we find that charging an AlTi bilayer sample with hydrogen reduces the ion beam mixing rate due to 600 keV Xe ions by a factor of 4.
