Abstract

High-temperature modification (T = 77 K) of strip-like Co₇₂Fe₅Si₁₁B₁₂, Co_73,6Fe_3,2Mn_3,2Si₅B₁₅ and Co_73,6(Fe, Ni, Mo, Mn)_5,7(Si_0,2B_0,8)₂₁ amorphous alloys was performed for the first time. Corrosion resistance of such modified strips in 0.15 M aqueous solution of NaCl was evaluated by different physicochemical methods. It was established that as a result of low-temperature processing some change in the morphology and elemental composition, as well as the orderliness of the structure of cobalt amorphous alloys occurs, which leads to a change in the electrochemical parameters. The possibility of using this treatment for the modification of cobalt-based amorphous metal alloys is shown.
