摘要：

The influence of heat treatments on the anodic behaviour and on the structure of Fe34Ni36Cr10P14B6 amorphous alloy, in 1 N H2SO4 and 1 N HCl solutions, has been studied by standard electrochemical techniques associated with X-ray diffraction analysis, differential scanning calorimetry and Auger electron spectroscopy. The as-quenched amorphous alloy displays very good corrosion performance in the testing environments. Heat treatments (from 150 to 500-degrees-C) induce structural relaxation processes and the amorphous to crystalline transition, thus bringing about contrasting effects on the corrosion resistance of the material. A superior performance has been observed in specimens annealed for 2 h at 350-degrees-C. The presence of an oxide surface layer is revealed by AES. A detailed analysis of the influence of structural and compositional aspects is given.
