The invention relates to a method for detecting
electrochemical corrosion and durability of a PET (
Polyethylene Terephthalate)-based
adhesive tape in an
electrolyte in the field of intelligent manufacturing, which comprises the following steps: acquiring initial surface
topography data of a material in an electrochemical environment, and determining
microstructure characteristics according to the initial surface
topography data; acquiring
electric field distribution data in the electrochemical environment, and determining
ion migration characteristics according to the
electric field distribution data; determining the initial
corrosion state of the surface of the material according to the
ion migration characteristics and an electrochemical impedance
spectroscopy measurement value; obtaining
corrosion morphology evolution data according to the
surface corrosion initial state; determining
corrosion-
dissolution associated parameters according to the
corrosion morphology evolution data and the concentration data of the dissolved matter in the
electrolyte; according to the corrosion-
dissolution associated parameters, analyzing the dynamic relationship between the microscopic change of the surface of the material and the concentration of the dissolved substance to obtain the tolerance degradation trend of the material; and predicting a durability
evaluation result of the material in a long-term electrochemical environment according to the tolerance degradation trend of the material.
