The method comprises the steps of firstly soaking the metal and the metal alloy in corrosion inhibitor solution with certain concentration, taking out a sample after a period of time, depositing or covering a layer of plasmon nanometer material film on the surface of the sample, and then detecting the Raman signal of the corrosion inhibitor molecules adsorbed on the surface of the sample by using a Raman spectrometer. The invention obviously amplifies the Raman signal of the corrosion inhibitor molecule by utilizing the surface enhanced Raman effect, can realize the high-sensitivity detection of trace corrosion inhibitor, is beneficial to promoting the deep analysis of the corrosion inhibition mechanism, and has wide application prospect in the research field of corrosion and protection.
