鎳鉻低合金鋼水蒸汽下的氧化動力學

Kinetic of Oxidation of Ni-Cr Low Alloying Steel under Vapour Atmosphere

摘要: 在純水蒸汽環境下,研究了鎳鉻低合金鋼等溫氧化過程中水蒸汽通入量與氧化膜厚度與時間的關系。結果表明,鎳鉻低合金鋼在水蒸汽環境中,氧化膜厚度與水通入量呈雙曲線關系,與溫度呈直線關系。對實驗結果回歸分析,得出了在水蒸汽下等溫氧化時氧化膜厚度與水通入量、溫度的關系方程。

Abstract: The kinetic of oxidation of Ni-Cr low alloying steel under vapour atmosphere is investigated.Several curves is obtained,which indicate that such variables as vapour quantity,temperature and time influence differently on the thickness of oxidation layer on Ni-Cr low alloying steel surface.
