| Abstract: | Alumina coating is used to improve the performance of high-temperature oxidation resistance,which can be fabricated on the surface of hydrogen resistance steel by two methods,thermal oxidation of arc ion plated Al coating and reactive magnetron sputtering.Elemental composition,structures and surface morphologies of the coating were analyzed and compared in this paper.The surface of the coatings,which was made by the first method,was composed of α-Al2O3 phase and internal was Fe-Al alloy phase.The Alumina coatings made by the second method were amorphous.In addition,appearances of Alumina coatings fabricated by these two methods were quit different,which were grey and transparent respectively.Both of the two kinds of coatings meet to the needs of high-temperature oxidation resistance. |
