Abstract
We analyze the susceptibility of low-carbon and low-alloy pipe steels and two types of rotor steel to corrosion cracking as a function of polarization in a NACE solution. It is shown that anodic and cathodic polarization inhibit the process of corrosion cracking only if the potential is shifted by 0.4–0.6 V. At the same time, full protection against cracking is never attained in testing at slow strain rates (10−5 sec−1). According to the results of the analysis of the diagrams of thermodynamic stability and measurements of the parameters ϕ and pH, sulfide cracking is initiated in the region of equilibrium between Fe2+ and FeS2 or between Ni2+ and NiS2 (NiS) if steel is alloyed with nickel.
