    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.
