Method for constructing corrosion resistance-mechanical property analysis model for metallic material and application thereof

A method for constructing a corrosion resistance-mechanical property analysis model for a metallic material, comprising the following steps:

• using a metallic material as a test object, acquiring test values of a corrosion parameter at different equivalent corrosion time points under a corrosion test condition to obtain a corrosion performance test experimental dataset, and acquiring test values of a mechanical parameter at different corrosion degrees corresponding to the different equivalent corrosion time points to obtain a mechanical property test experimental dataset;
• wherein the corrosion test condition is used to simulate a target service environment of the metallic material;
• and the corrosion parameter comprises at least one of a corrosion degree and a corrosion rate;
• and
• establishing, based on the corrosion performance test experimental dataset, a first set of empirical relational expressions describing variation of the corrosion parameter with equivalent corrosion time, and establishing, based on the mechanical property test experimental dataset, a second set of empirical relational expressions describing variation of the mechanical parameter with equivalent corrosion time.
