Abstract (EN): Depth profiles of tungsten implanted into aluminium were studied as a function of the annealing temperatures using the Rutherford backscattering technique. The formation of the Al12W metastable alloy starts at a temperature of 450° C. Electrochemical corrosion studies show a shift in the corrosion potential of + 600 mV for the as-implanted samples relative to the nonimplanted ones. This shift is 50 mV lower for samples where the Al12W metastable alloy has been formed. However, the implanted samples show higher corrosion rates than the nonimplanted ones. © 1990.
