Abstract
Corrosion fatigue, mechanical properties and mechanochemical effect (the effect of mechanical deformation on the surface electrochemical reactions) were investigated in some Mg-based alloys supposing that aluminum alloying influences them. A simple method of testing mechanoelectrochemical behavior and corrosion fatigue of alloys was developed. Potentiostatic polarization measurements on stressed electrode were carried out in chloride electrolyte. The correlation between the mechanoelectrochemical behavior and strain hardening stages is observed during plastic deformation. Maximum mechanochemical effect is achieved under intense strain hardening in the initial portion of this stage. The highest resistance to developing mechanochemical effect is obtained for the alloys with the lowest AI content. The experimental observations are explained theoretically. The features of the mechanoelectrochemical behavior of different Mg-alloys are confirmed by corrosion fatigue tests.
