- 摘要:
- 以 HRB400 钢筋作为基体材料，锌 - 锰系磷化后分别采用脱水防锈油、硅酸盐溶液、铈盐溶液进行封闭处理。采用扫描电镜、能谱仪、测厚仪、接触角测量仪和电化学工作站对常规磷化膜及封闭处理后磷化膜的形貌、成分、厚度和疏水性进行测试分析，并研究常规磷化膜及封闭处理后磷化膜在模拟混凝土孔隙液中的耐蚀性。结果表明：磷化后钢筋基体上生成一层覆盖完整、表面呈片状结构的磷化膜，浸油封闭后磷化膜的形貌、成分、厚度和表面疏水性未出现明显变化，耐蚀性略有提高。而硅酸盐封闭和铈盐封闭后磷化膜的致密性明显改善，成分和表面疏水性都发生变化，耐蚀性明显好于常规磷化膜和浸油封闭磷化膜。采用铈盐溶液封闭后磷化膜的结晶缺陷得到有效修复，并且表面呈现疏水性，对腐蚀介质具有更强屏蔽阻挡效果，增大了腐蚀阻力，从而明显提高钢筋在模拟混凝土孔隙液中的耐蚀性。
- Abstract:
- ： HRB400 rebar was treated by zinc-manganese phosphating process ， followed by sealing treatment using dehydrated antirust oil ， silicate solution and cerium salt solution respectively. Scanning electron microscope ， energy dispersive spectrometer ， thickness meter ， contact angle meter and electrochemical workstation were used to test and analyze the morphology ， composition ， thickness and hydrophobicity of conventional phosphating film and the phosphating film after sealing treatment ， and the corrosion resistance of conventional phosphating film and the phosphating film after sealing treatment in simulated concrete pore solution was studied. The results show that a phosphating film with flaky structure is formed on the surface of rebar matrix. The morphology ， composition ， thickness and surface hydrophobicity of the phosphating film do not change significantly after oil immersion sealing ， and the corrosion resistance is slightly improved. However ， the compactness of the phosphating film after silicate sealing and cerium salt sealing is obviously improved ， the composition and surface hydrophobicity are changed ， and the corrosion resistance is obviously better than that of conventional phosphating film and the phosphating film after sealing treatment. After sealing treatment using cerium salt solution ， the crystallization defects of the phosphating film can be effectively repaired ， and the surface is hydrophobic ， which has a stronger shielding effect on the corrosive medium and increases the corrosion resistance ， thus significantly improving the corrosion resistance of the rebar in the simulated concrete pore solution.
