× 10 annealing is a process that is deleterious for the corrosion resistance of the electrodeposited amorphous alloys. Figure 12 shows typical polarization curves obtained for the selected Ni66Cr12P22 and Cr coatings heat treated at 400 °C compared with those obtained for the corresponding as-electrodeposited Ni-Cr-P and Cr coatings. This figure shows that the annealing decreases the corrosion resistance of both coating
