<p>PROBLEM TO BE SOLVED: To provide a method for evaluating deterioration of a coating film, capable of more accurately estimating a degree of degradation of the coating film.SOLUTION: The method for evaluating deterioration of a coating film comprises: creating a model showing a relation between adhesive force, and a storage elastic modulus and a loss elastic modulus on the basis of measurement results of the adhesive force in a time range in which the adhesive force deteriorates with the passage of time, the storage elastic modulus and the loss elastic modulus; and estimating a degree of degradation of a coating film to be inspected on the basis of the model, the storage elastic modulus and loss elastic modulus of the coating film to be inspected. Thereby, degradation of the coating film can be more accurately estimated even when the degradation of the coating film is not revealed in the appearance or the adhesive force.</p> |
