Optimization of Pickling Solution for Improving the Phosphatability of Advanced High-Strength Steels

Optimization of Pickling Solution for Improving the Phosphatability of Advanced High-Strength Steels

This study investigated the optimum pickling conditions for improving the phosphatability of advanced high-strength steel (AHSS) using surface analysis and electrochemical measurements. To remove the SiO<sub>2</sub> that forms on the surface of AHSS, 30 wt.% NH<sub>4</sub>HF&...
