Abstract:
Properties and corrosion resistance of the electrophoretic paint films on two types of uncoated press-hardened 22MnB5 steels (cold-rolled and CSP hot-rolled) and an Al-Si steel based on 22MnB5 were compared in the present contribution. The physicochemical properties of the electrophoretic paint films on these three types of press-hardened steels were found to be proximal, and all meet the requirements of related standards of automobile manufacturers. The corrosion resistance of unpainted press-hardened samples of the three kinds of materials was found to be poor. The poor corrosion resistance of the Al-Si sample is related to the high iron concentration and the presence of microcracks in the coating after hot-stamping process.
