Recent progress in corrosion resistant amorphous alloys
Corrosion behavior of sputter-deposited amorphous Al-W alloys in hydrochloric acid was compared to that of pure aluminum and tungsten metals. Both d.c. polarization and a.c. impedance studies clearly show that an increase of tungsten content in the alloy lowers the overall rate of corrosion and increases the critical pitting potential. The corrosion rate of amorphous Al-W films is about two orders of magnitude lower than that of aluminum, and the corrosion potential, E_corr, is about 500 mV higher than that of aluminum. Before and after exposure to corrosive environment, the structure of prepared films was investigated using X-ray diffraction method. The films prepared in the range of compositions from Al_80W_20 to Al_67W_33 were completely amorphous.
