Review on Corrosion Test Methods and Evaluation Techniques for Materials in Atmospheric Environment

In this article, the research progress of atmospheric corrosion test methods is reviewed, namely atmospheric corrosion accelerating test method, atmospheric corrosion electrochemical test meth¬od and atmospheric corrosion monitoring and detecting technology. Among the atmospheric corrosion ac¬celeration test methods, the multi-factor cyclic corrosion test has become the main development direction of simulated atmospheric corrosion acceleration tests. At the same time, due to the improvement of the spatial resolution, the electrochemical test methods for atmospheric corrosion have also been extended from macroscopic electrochemical technology to micro-area electrochemical technology. In addition, with the development of the Internet of Things and computer technology, modern data processing technology based on data mining and machine learning has also been applied in atmospheric corrosion monitoring and testing technology.
