摘要: 研究了電鍍鋅鋼板CrO₃-H₃PO₄-SiO₂體系純化膜的成分與結構,并對鈍化膜的耐蝕性及其原因進行了探討.結果表明,該鈍化膜是1種由CrO₃,Cr(OH)₃,CrOOH,ZnCrO₄,ZnSiO₃Zn₃(PO₄)₂,CrPO₄和SiO₂等化合物組成的、具有凝膠網絡狀結構的厚型復合轉化膜.這種膜具有良好的屏蔽效應和緩蝕作用,能明顯地改善鍍鋅鋼板抗白銹的能力.它的耐蝕性是CrO₃-SiO₂體系鈍化膜的3倍.

Abstract: The composition and structure of passive film formed from CrO₃-H₃PO₄SiO₂, systems on galvanized steel sheet were inveshgated, the corrosion resistance and its protective causes of the film were also discussed. The experimental results showed thatthe film is a thick type of complex conversion coating with gelatinous net structure containing CrO₃, Cr(OH)₃, CrOOH, ZnCrO₄, ZnSiO₃, Zn₃(PO₃)₂, CrPO₄ and SiO₂, etc. The white rust-resisting property of the film is of three times better than that of film formed from CrO₃-SiO₂, systems because of good shielding and inhibiting.
