详细
The corrosion resistance of metallic amorphous alloys (AAs) Fe80.2P17.1Mo2.7, Fe80.5P18.4Nb1.1, Fe98 –xPxSi2 (x = 14, 16, 20), Fe76.5P13.6Si4.8Mn2.4V0.2C2.5 in a 0.1 M solution of Na2SO4 (pH 6.25) and its change due to structural relaxation, nanocrystallization, and local deformation are studied. The activation of structural relaxation by photonic treatment is shown to increase the corrosion resistance of AAs. As the phosphorus content in the Fe98 ‒ xPxSi2 system decreases, the corrosion resistance of AAs decreases because of partial crystallization, which is accompanied by the formation of iron phosphides during rapid cooling of a melt, and silicon segregation at phase boundaries. The formation of local deformation zones in the near-surface layer of Fe76.5P13.6Si4.8Mn2.4V0.2C2.5 AA decreases its corrosion resistance. The niobium alloying of Fe‒P AAs is shown to be effective to decrease the corrosion rate.
