| 中文摘要: |
| 以浸泡法在化学氧化处理前后的 316 L 不锈钢表面制备了植酸自组装膜,通过动电位扫描、SEM观察及 FT-IR 测试,研究了组装液 pH 与组装时间对植酸自组装膜吸附行为及耐蚀性能的影响。 结果表明:植酸被成功地组装到 316 L 不锈钢表面,并使其耐腐蚀性能大大提高。 相比而言,化学氧化处理有利于形成更致密、更耐腐蚀的自组装膜。 不经化学氧化处理时,植酸组装的最佳 pH 为 6 . 90 ,最佳时间为 12 h;而经化学氧化处理时,植酸组装的最佳 pH 也为 6 . 90 ,但最佳时间缩短为 4 h。 |
| 英文摘要: |
| The phytic acid self-assembled film ( SAM) was prepared on 316 L stainless steel surface before and after chemical oxidation by immersion method. The effect of SAM solution pH and SAM time on the adsorption behavior and corrosion inhibition performance of the phytic acid SAM was investigated by potential dynamic scan, SEM ( scanning electron microscope) observation and FT-IR ( Fourier transformed infrared spectroscopy) testing. The experimental results show that phytic acid has been successfully assembled to the surface of 316 L stainless steel,which greatly improves the corrosion resistance of the metal .The chemical oxidation pretreatment is beneficial for the formation of a denser SAM with more notable corrosion resistant performance. For the samples without chemical oxidation treatment, the optimum pH for the assembly of phytic acid is 6 . 90 and the best assembly time is 12 h. And for those with chemical oxidation, the optimum pH is still 6 . 90 while the best assembly time reduces to 4 h. |
