Abstract — Effects of bench loading and stresses on the corrosion resistance of 16 alloy are studied. Complicated effect of the stress intensity and the cyclic loading on the surface morphology and pit concentration is demonstrated. Harmonic character of the loading dependence of the change of corrosion resistance is due to segregation effects.
