摘要：

A Ti3Al(O)-Al2O3 in situ composite was explored as a coating system for Ti using thermal spray. Oxidation tests at 700-800 degreesC showed that this coating remarkably decreased the oxidation rate and increased the scale spallation resistance compared with Ti. The mechanisms for these improvements were then briefly discussed. (C) 2003 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
