Phosphate-silane coatings were developed on the Q235 mild steel by incorporating poly(dopamine) modified h-BNs into the zinc phosphating bath to enhance the corrosion resistance. The effects of PDA modified h-BNs with varying concentrations (0.10–0.90 g/L) on the surface modification, and corrosion resistance of the composite coatings were investigated. Results show that denser and uniform coatings were achieved for samples containing poly(dopamine) modified h-BN. Sample 0.60 g/L attained outstanding corrosion resistance, which is in one order of magnitude lower than the pure coatings with a current density of 1.95 × 10⁻⁵ A/cm². Modified h-BN effectively accelerates and enhances the corrosion resistance of the phosphate-silane coatings.

通过将聚（多巴胺）改性的h-BNs掺入锌磷化液中以增强耐蚀性，在Q235低碳钢上开发了磷酸盐硅烷涂层。研究了不同浓度（0.10–0.90 g / L）的PDA改性h-BNs对表面改性和复合涂层耐蚀性的影响。结果表明，含有聚（多巴胺）改性的h-BN的样品获得了致密均匀的涂层。样品0.60 g / L获得了出色的耐腐蚀性，比电流密度为1.95×10 ^-5 A / cm ²的纯涂层低了一个数量级。改性的h-BN有效地促进和增强了磷酸盐硅烷涂层的耐腐蚀性。
