| 英文摘要 | In this study, two modified MCrAlY-type coatings were prepared by the same arc ion plating process. 'Gradient annealing' and 'gradient annealing plus preoxidation' were adopted as post-treatments for the two coatings. A two-layer scale of a mixed oxide layer and a pure alumina layer with the alumina next to the substrate was formed on the latter coating. A cyclic hot corrosion test was carried out on them with a conventional MCrAlY-type coating as a reference. The kinetics and evolution of the microstructure showed them to have greater hot corrosion resistance at 900 degrees C. The preformed inner alumina scale by preoxidation retarded the occurrence of internal oxidation-sulphidation to some extent. Additionally, the internal sulphidation-oxidation model is elucidated and extended. |
