Determination of the Mechanism of Tribocorrosion of D16T Alloy According to the Electrode Potential

We study the influence of the contact speed of friction surfaces on the tribocorrosion behavior of D16Т alloy in acid rain. It is shown that the electrode potential, the friction coefficient, and the loss of material in the course of tribocorrosion qualitatively are well correlate and depend on the...

Description
Summary:We study the influence of the contact speed of friction surfaces on the tribocorrosion behavior of D16Т alloy in acid rain. It is shown that the electrode potential, the friction coefficient, and the loss of material in the course of tribocorrosion qualitatively are well correlate and depend on the velocity of mutual displacement of the surfaces of friction couples. It is demonstrated that the activation potential, corrosion potential, and tribological potential enable one to estimate the fracture mechanism of materials passivated in corrosive media.
