Preparation And Corrosion Property Of Co68fe7-Xcrxsi15b10 Amorphous Alloy
INTERNATIONAL JOURNAL OF ELECTROCHEMICAL SCIENCE(2015)
Abstract
Co68Fe7-xCrxSi15B10 (x=0, 1.5, 3, 4.5) amorphous ribbons were prepared by melt-spinning technique. Influences of Cr content on the soft magnetic property and corrosion resistance under sulfuric acid were systematically studied. Results indicate that after adding Cr elements, the coercivity of alloys was decreased significantly. The addition of Cr element can greatly improve the corrosion resistance of Co-Fe-Si-B amorphous alloys. Co68Fe4Cr3Si15B10 has the best soft magnetic property and lowest hysteresis loss with significant improved corrosion resistance.
