摘要

本研究考察了等离子涂层T12钢在工业锅炉中100小时10次循环的热腐蚀行为。该涂层含有碳纳米管增强的氧化铝-二氧化钛粉末。将基材暴露在750℃的锅炉中。采用热重法对腐蚀动力学进行了评价。腐蚀循环结束后，用扫描电子显微镜和x射线衍射分析检查腐蚀样品。该研究表明，碳纳米管增强涂层在锅炉环境中比传统氧化铝涂层具有更好的耐腐蚀性。

Development of CNT reinforced Al2O3-TiO2 coatings for boiler tubes to improve hot corrosion resistance

This study examines the hot corrosion behaviour of plasma-coated T12 steel for 10 cycles of 100 h each in an industrial boiler. The coating contains CNT (carbon nanotubes) reinforced alumina-titania powders. The substrates were exposed to the boiler at 750 °C. A thermogravimetric examination was conducted to evaluate the kinetics of corrosion. Corroded samples were examined with scanning electron microscopy and x-ray diffraction analysis after the end of the corrosion cycle. This research study concludes that CNT-reinforced coatings provide better corrosion resistance than conventional alumina coatings in the boiler environment.
