| 中文摘要 | Al2O3 thin films were deposited on a Ti3Al based alloy (Ti-24Al-14Nb-3V-0.5Mo-0.3Si) by sol-gel processing. Isothermal oxidation at temperatures of 900-1000 degrees C and cyclic oxidation at 800-900 degrees C were performed to test their effect on the oxidation behavior of the alloy. Results of the oxidation tests show that the oxidation parabolic rate constants of the alloy were reduced due to the applied thin film. This beneficial effect became weaker after longer oxidation time at 1000 degrees C. TiO2 and Al2O3 were the main phases formed on the alloy. The thin film could promote the growth of Al2O3, causing an increase of the Al2O3 content in the composite oxides, sequentially decreased the oxidation rate. Nb/Al enriched as a layer in the alloy adjacent to the oxide/alloy interface in both the coated and uncoated alloy. The coated thin film decreased the thickness of the Nb/Al enrichment layer by reducing the scale growth rate. (c) 2005 Elsevier B.V. All rights reserved. |
