Abstract: A method for monitoring mechanochemical activation of metal powders in dynamic electrochemical environment and a device thereof are provided. The method includes constructing a dynamic testing environment in an electrochemical cell, using a three-electrode system, and collecting data from an external electrochemical workstation. The three-electrode system is composed of the working metal plate, the reference electrode, and the platinum electrode. The dynamic testing environment includes small load impacts and changes in pH and composition of the solution. Under the premise of simulating the production environment of the mechanical plating and the water-based metal coating material, the monitoring method described in the present disclosure cooperates with an electrochemical workstation for OCPT testing to achieve the monitoring of mechanochemical activation of metal powders in dynamic electrochemical environment.
