摘　　要：A novel Ti/MnO2 reference electrode (TMRE) used for concrete environment was fabricated by the electro-deposition method and encapsulated carefully.The properties of the electrode were characterized by open-circuit potential,potentiodynamic polarization behavior in synthetic concrete pore solutions and electrochemical performance in cement mortar.The experimental results indicate that the TMRE shows good stability with and without the addition of Cl-ions and desirable polarization behavior in synthetic pore solution.Results of tests in cement mortar indicate that the potential of TMRE will be stable after about 7 days.The stability and desirable polarization behavior make it a promising reference electrode for concrete environment.A novel Ti/MnO2 reference electrode (TMRE) used for concrete environment was fabricated by the electro-deposition method and encapsulated carefully.The properties of the electrode were characterized by open-circuit potential,potentiodynamic polarization behavior in synthetic concrete pore solutions and electrochemical performance in cement mortar.The experimental results indicate that the TMRE shows good stability with and without the addition of Cl-ions and desirable polarization behavior in synthetic pore solution.Results of tests in cement mortar indicate that the potential of TMRE will be stable after about 7 days.The stability and desirable polarization behavior make it a promising reference electrode for concrete environment.
