Zusammenfassung: | The invention provides a method for evaluating the residual life of an anticorrosive coating, and relates to the technical field of in-service anticorrosive coating safety monitoring. The evaluation method comprises the following steps: performing a corrosion test on an anticorrosive coating in a preset environment, and obtaining corrosion characteristic parameters including electrochemical parameters and an infrared absorption peak value of a preset wavelength; repeating the corrosion test on the anti-corrosion coating until the anti-corrosion coating is completely invalid to obtain a plurality of electrochemical parameters and infrared absorption peak values at a plurality of preset wavelengths; fitting the electrochemical parameter and the infrared absorption peak value of the preset wavelength to obtain a first fitting parameter corresponding to the electrochemical parameter and a second fitting parameter corresponding to the infrared absorption peak value of the preset wavelength; and according to the fi |
