| 目的 提高304不锈钢表面的耐蚀性。方法 选取304不锈钢为基体，采用溶胶凝胶法，制备陶瓷涂层。以异丙醇铝为前驱体制备Al2O3溶胶。通过XRD对干凝胶粉末进行物相分析，并对陶瓷涂层的耐腐蚀性能进行了研究，分析了制备溶胶的原料配比、胶溶剂的加入量、不同烧结温度对陶瓷涂层表面形貌和耐腐蚀性能的影响。结果 n异丙醇铝: n无水乙醇: n去离子=1:1:100、水浴温度70 ℃、pH=4~5时搅拌制备出的溶胶，在600 ℃下保温30 min可制备出无裂纹、均匀、高纯、表面质量良好的陶瓷涂层，陶瓷涂层为高纯的Al2O3。结论 陶瓷涂层在NaCl溶液和盐雾中表现出优异的耐蚀性。 |

| The work aims to improve corrosion resistance of 304 stainless steel surface. With 304 stainless steel as substrate and aluminum isopropoxide as precursor, Al2O3 sol was prepared in the sol-gel method. Xerogel powder was subject to phase analysis with XRD, and corrosion resistance of the ceramic coating was studied, effects of raw materials ratio, amount of peptizer and different sintering temperature on surface morphology and corrosion resistance of the ceramic coating were determined. The sol as-prepared was stirred provided with ratio of ethanol to deionized water of 1:1:100, water bath temperature of 70 ℃ and pH of 4~5. A crack-free ceramic coating featuring in uniformity, high purity and good surface quality could be prepared after thermal insulation at 600 ℃ for 30 min. Ceramic coating was composed of high purity Al2O3. The ceramic coating exhibits excellent corrosion resistance in NaCl solution and salt fog. |
