Surface passivation effect on the static coke deposition of kerosene at supercritical pressure

National Key Laboratory on Aero-Engines, Beijing University of Aeronautics and Astronautics, Beijing 100191, China

摘要

摘要: 通过静态装置,研究了不锈钢经表面磷化、酸洗钝化以及电解钝化后对超临界压力下航空煤油RP-3热氧化结焦的抑制效果,并对表面钝化层的耐久性做出评估.研究发现,不锈钢的钝化膜层有效地降低不锈钢表面催化活性,按结焦抑制效果排序为:电解钝化>酸洗钝化>磷化;化学稳定性好、耐蚀性强的钝化膜层会延长材料的使用寿命,按钝化膜耐蚀性排序为:电解钝化>酸洗钝化>磷化;综合结焦抑制效果及化学稳定性两个因素考虑,电解钝化为最佳表面钝化方案,但其在高温高腐蚀的煤油环境下长时间实验时易失去钝化效用.

Abstract: Experiments were performed to investigate surface passivations-effect on coking reaction of aviation kerosene RP-3 fuel, and to evaluate the chemical durability of passivating films via the static experiment system at the supercritical pressure. The results reveal that: surface passivation technology on stainless steel can effectively suppress RP-3 coke deposition, the sequence of inhibitory effects of coke deposition from the highest to the lowest is below: electrolytic passivation > acid cleaning passivation> phosphating; The work life of materials depends on chemical durability of passivating films, the sequence of chemical durability of passivating films from the highest to the lowest is below: electrolytic passivation > acid cleaning passivation> phosphating; Based on an overall consideration of various factors, electrolytic passivation is the best option, but out of action at high temperature and high corrosive environment for the long time experiment.
