NITRATION EFFECTS ON STAINLESS STEEL CORROSION RESISTANCE (in Russian)
Electrode potentials of 4X14H2B2 (0.42% C, 13.75% Cr, 12.6% Ni, 1.5% W, 0.5% Mo, 0.4% Si, and 0.7% Mn) and 4X14H2B2 (0.4% C, 13.5% Cr, 2.68% Ni, 2% W, 0.55% Si, and 0.55% Mn) in 0.01 N of sodium chloride solution were investigated. The 4X14H14B2M steel was nitrated at 560 C for 48 hours; ammonium dissociation was 25 to 35%. The 4X14H2B2 was nitrated at 600 C for 24 hours. The changes in nitrated steel corrosion resistance, depending on the depth of the layer, corresponds to the changes in the electrode potential. The layers with low corrosion resistance and lowered electrode potentials, found at a certain depth of nitrated steels, were composed of chromium nitrides and solid solutions, impoverished by chromium and nitrogen.
