Abstract
The effect of silicon on the corrosion-electrochemical behavior of iron alloys containing 15, 20, and 25% chromium in a 1 N H2SO4 solution at room temperature is investigated. With the use of Mossbauer spectroscopy, the hyperfine magnetic and electronic structure of the alloys is studied. With the Normos program package for processing spectra, the distribution function of hyperfine magnetic fields P(Hef), mean intensity of the effective magnetic field H ef, isomeric shift, electric quadrupole splitting eq, and other parameters are calculated. Spectroscopic data are compared to the results of polarization measurements. A correlation between the hyperfine structure and electrochemical behavior of the alloys in various potential ranges is found.
