Abstract

In recent years, the press hardening steel with thin aluminum silicon coating independently developed by relevant domestic institutions has gradually been applied in the automotive industry. The issue of whether thin aluminum silicon coated press hardening steel can replace traditional aluminum silicon coated press hardening steel in terms of corrosion resistance has always been a concern for the domestic industry. This article compares the salt spray corrosion performance of three sets of samples, including traditional aluminum silicon coated press hardening steel and microalloyed thin aluminum silicon coated press hardening steel. The results showed that the weight loss rate and corrosion rate of the two groups of microalloyed samples in different states were lower than those of traditional aluminum silicon coated press hardening steel after salt spray corrosion treatment for 3–15 days, demonstrating better corrosion resistance. The refinement of the matrix structure of steel through microalloying treatment and the suppression of high stress corrosion tendency of steel quenching microcracks through thinning treatment of coatings may be the two main reasons for the stronger corrosion resistance of the second and third group samples.
