1 Introduction
The rapid development of the automobile industry has made automobiles an indispensable part of peoples daily life. It is the key component of the automobile industry that we face in our daily life. Since the automobile body is exposed to the air, sunshine, wind and rain all the year round, it is easy to be corroded by various corrosive environment such as acid and alkali, salt and dust. It is not only easy to cause the performance degradation of the car, but also even the failure of the automobile, thus leading to the potential safety hazard. In order to protect the automobile body from corrosion and effectively control the safety hazard, it is necessary to use anti-rust steel plate for automobile body.
However, the application of anti-rust steel plate for automobile body is not the same as other metals, and the application result is directly related to the corrosion index of the anti-rust steel plate. According to the traditional corrosion experiment, it is difficult to accurately estimate the anti rust steel plate corrosion situation. Therefore, it is necessary to apply corrosion prediction technology to accurately predict the corrosion life of automobile body anti-rust steel plate, and to provide a scientific basis for its selection, utilization, and corrosion prevention measures.
