Research on Evaluation of Corrosion Grade Based on Image Processing Technique

Abstract

The corrosion images of LY12CZ aluminum alloy with different corrosion time were obtained from accelerated corrosion experiment. The changing law of pits corrosion ratio at different corrosion time and corresponding corrosion grade were attained through image processing technique based on binary characteristic extraction. A new thought of corrosion damage evolvement law for aluminum alloy was proposed based on Corrosion grade which was regarded as the evaluation standard of corrosion damage for aluminum alloy.

Comprehensive Safety Evaluation of Corroded Circular Steel Tubes under Compression Based on Image Processing

“…Current research results of corrosion assessment methods [24][25][26][27][28][29][30] and specifications [31][32][33] for steel members are mostly focused on components such as underground pipelines, bridge cables, and steel gates, while few studies have been conducted on circular steel tube members. Additionally, the evaluation indicators and parameters employed in existing explorations are different.…”
