Abstract
The influence of Cr concentration on the corrosion resistance of Fe73.5Si13.5B9Nb3Cu1 and Co73.5Si13.5B9Nb3Cu1 metallic glasses was studied by DC electrochemical methods in different concentrations of H2SO4 (1, 3 and 5M) at room temperature. Gravimetric tests were performed to establish the reliability of the data obtained electrochemically. Every test was determined with the same material in different states: amorphous, nanocrystalline and crystalline. In all cases metallic glasses and nanocrystals showed better resistance to corrosion in the tested conditions with increasing chromium concentration. However, in test conditions, the Fe-based materials maintained a high corrosion rate. The corrosion resistance of Co-based materials was slightly greater than that of Fe-based materials.
