Specifities of forming electrochemical dissolution zones at ferrite-cementite-structured alloys in sulfuric acid solutions

Specific features of the formation of electrochemical dissolution zones at steels C^sub T^20 and C^sub T^45 with a ferrite-cementite structure, were revealed by combining electrochemical and metallographic methods. A possibility of developing the self-dissolution process at the ferrite/cementite bou...

Description
Summary:Specific features of the formation of electrochemical dissolution zones at steels C^sub T^20 and C^sub T^45 with a ferrite-cementite structure, were revealed by combining electrochemical and metallographic methods. A possibility of developing the self-dissolution process at the ferrite/cementite boundary is shown. A spontaneous sequence of the anodic dissolution of structural constituents of the alloys is found.[PUBLICATION ABSTRACT]
