AI Technical Summary
In existing technologies, the corrosion resistance testing methods for laser passivated stainless steel are too time-consuming and inefficient, making it difficult to meet the needs of rapid screening of large batches of samples.
By acquiring microscopic images and surface roughness parameters of laser-passivated stainless steel, morphological feature parameters are extracted. Combined with a preset microscopic morphology type-corrosion resistance correspondence table, the corrosion resistance level can be directly determined, avoiding electrochemical testing.
It enables rapid and intuitive determination of the corrosion resistance level of laser passivated stainless steel, improving detection efficiency by more than 100 times, shortening the process optimization cycle, and reducing R&D costs.
