<p>PROBLEM TO BE SOLVED: To easily measure the corrosion rate of a metal component at a high reproducibility without requiring much labor.SOLUTION: On the basis of an initial value, a measured value after exposure, the density of a component, the density of a metal corrosion product occurring in an environment, and the weight fraction of the metal in the corrosion product, the physical quantity of a metal part obtained by removing the corrosion product from the component after the exposure in the environment for a set duration is calculated. Thus, a calculated value is obtained. Then, in the step S105, the corrosion rate is calculated on the basis of the relationship between the difference between the initial value and the calculated value and the exposure duration.</p> |
