Stress corrosion cracking of FeCoBSi metallic glasses in HCl solutions

Abstract

In general, one may suggest that all the Fe-Co-B-Fe metallic glasses have good corrosion resistance, especially those with high Co content. Additions of Ni, Mn and Mo are known to further enhance the corrosion resistance of metals. In this investigation, the susceptibility of Fe[sub 78]B[sub 13]Si[sub 9], Fe[sub 66]Co[sub 18]B[sub 15]Si[sub 1], Co[sub 66]Fe[sub 4]Ni[sub 1]B[sub 14]Si[sub 15], Co[sub 76]Fe[sub 2]Mn[sub 4]B[sub 12]Si[sub 6] and Co[sub 69] Fe[sub 4]Ni[sub 1]Mo[sub 2]B[sub 12]Si[sub 12] glasses to stress-corrosion cracking in the HCl solution were examined. The examinations were carried out under bending stress.
