Title:
CORROSION SPEED ESTIMATION DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2021/100193
Kind Code:
A1
Abstract:
This corrosion speed estimation device for estimating the corrosion speed of metal disposed in a prescribed environment comprises: an input unit 10 for inputting water composition information about, for example, moisture content (hydration time), temperature, conductivity, and soil type; a corrosion speed estimation model 20 for receiving the water composition information about environmental water composition as an input and using the water composition information to estimate the corrosion speed of metal disposed in the environment; and an output unit 30 for outputting the estimated metal corrosion speed to the outside. The corrosion speed estimation model 20 is generated using a machine learning algorithm such as a random forest, neural network, or RNN (LSTM).
