Mechano-electrochemical effect between erosion and corrosion

摘要

The characteristics and mechanisms of the mechano-electrochemical effect were investigated both theoretically and experimentally for two steels (AISI 1020 and 52100) in various heat-treated conditions subjected to sequential erosion and corrosion. A mathematical equation is developed to describe the mechano-electrochemical effect in which the corrosion rate is exponentially related to the change of corrosion potential and increased stored strain energy.
