MECHANISM OF METAL CORROSION IN NARROW SLITS AND CREVICES

Abstract

The corrosion of Mg and its alloys in narrow slits were studied. It was shown that in the majority of cases these metals are subjected to greater corrosion in slits than in electrolytes. The dependence of the velocity of corrosion on the dimension of slits is described by complicated curves characterized by the presence of maxima at certain values of the width of the slit. Intensified corrosion of Mg and its alloys is not caused by O diffusion but chiefly by the bubbles of H mixing the electrolyte. The movements of bubbles prevent the formation of protective films and cause the destruction of existing ones.
