中文摘要: |
采用扫描电镜( SEM) 、能谱分析( EDS) 、电化学测试和中性盐雾试验对经过氟硅酸钾溶液封闭处理后的氟铁酸钾转化膜的表面形貌、元素组成和耐蚀性进行了分析测试。 结果表明,氟硅酸钾水解产生的 SiO2胶体对钢铁表面氟铁酸钾转化膜的封闭作用使得钢铁样品的腐蚀电流密度降低,防腐性能增强。 |
英文摘要: |
The surface morphology, element composition and corrosion resistance of potassium fluoferrite conversion coating after fluosilicate sealing were tested by scanning electron microscope, energy-dispersive spectroscopy, electrochemical test and neutral salt spray test . The results show that the sealing of SiO2colloid from potassium fluosilicate hydrolysis on potassium fluoferrite conversion coating make steel corrosion current density decrease and anti-corrosion performance increase. |
