Abstract

Aiming PHS 2GPa material and its B-pillar products at object, through the accelerated corrosion procedure, firstly, weight loss and corrosion data are collected to analyze the corrosion rate of metal materials and the compatible performance of the substrate/layer; secondly, and tensile strength and elongation are collected at break, to analyze the residual mechanical properties of the steel matrix; finally, combined with the weight loss and mechanical properties data, the migration behavior of the corrosion mechanism under different corrosion cycles is analyzed. The results show that pitting corrosion occurs at the defect position of the oxide layer on the metal surface, and pitting corrosion can increase the material difference. When the weight loss is 0.92%, the mechanical properties are reduced by about 10.46%. Uniform corrosion can weaken the effect of pitting or perforation on the body, and the mechanical properties of materials are stable. The elongation at break of most samples is <10%, which meets the performance requirements of high-strength steel for vehicles.
