摘要：
A phenomenological model of the dependence of the critical temperature of pitting formation in 06KhN28MDT (ÉI 943) alloy on its heterogeneity in a chloride-containing medium has been developed. Based on the results of our investigations and analysis of the available literature data, we propose to use the quantitative volume of nonmetallic inclusions V taking part in the pitting formation in the alloy as an index of its heterogeneity. We have established a linear dependence between the critical temperature of pitting formation in this alloy and the index V in a chloridecontaining medium. Using the results of regression analysis, we have obtained mathematical dependences of the critical temperature of pitting formation on f(V) for aqueous solutions with pH from 4 to 8 and chloride concentrations of 350, 400, 500, 550, and 600 mg/liter.
