| 中文摘要 | The joining of titanium aluminum carbides has been successfully performed at high temperature and low oxygen partial pressure. The mechanism of the bonding is attributed to the preferential oxidation of At atoms in the titanium aluminum carbides at low oxygen partial pressure, which leads to the formation of an Al(2)O(3) layer through the joint interface. The specimens joined at 1400 degrees C exhibit a high flexural strength of 315 +/- 19.1 MPa for Ti(2)AlC and 332 +/- 2.83 MPa for Ti(3)AlC(2), which is about 95% and 88% of the substrates, respectively, and the high flexural strength can be retained up to 1000 degrees C. The high mechanical performance of the joints is attributed to the similar density and thermal expansion coefficient values of Al(2)O(3) to those of the Ti(2)AlC and Ti(3)AlC(2) substrates. It indicates that bonding via preferential oxidation at low oxygen partial pressure is a practical and efficient method for Ti(2)AlC and Ti(3)AlC(20) (C) 2009 Elsevier Ltd. All rights reserved. |
