Comparative Study on Filiform Corrosion of Automotive Hot Dip Galvanized and Zn‐Al‐Mg Coated Steels Under Acetic Acid Accelerated Test

ABSTRACT Acidic residues trapped in automotive structural crevices, where incomplete paint coverage often occurs due to electrodeposition electric‑field shielding, can initiate filiform corrosion (FFC). This study develops an accelerated test using 0.5 M acetic acid (50°C, 95% RH...
