Classification: CPC G | IPC G

Claim 0:
1. A corrosion rate estimation apparatus comprising:
a corrosion rate measurement unit adapted to repeat water supply cycles in which water is supplied to soil in which a metal to be evaluated is buried, and to measure a cycle number of each water supply cycle, one or more time points in each water supply cycle, and a corrosion rate of the metal at the one or more time points;
a learning unit adapted to find a prediction model using the cycle number, the one or more time points, and the corrosion rate as input to a machine learning algorithm, the prediction model representing a future corrosion rate; and
a corrosion rate estimation unit adapted to assign a particular cycle number and a time point in a particular cycle at which a desired corrosion rate is to be estimated to the prediction model, and to estimate the desired corrosion rate of the metal at the time point.
