摘要: 由于陶瓷与金属的热物理性能不匹配,使得陶瓷/金属连接接头在焊后往往产生巨大的残余热应力.在陶瓷、陶瓷基复合材料连接研究领域,几乎一直伴随着缓解陶瓷/金属连接接头残余热应力的方法研究.综述了国内外几十年来的研究成果,总结出7种缓解陶瓷/金属连接接头残余热应力的方法,其中缓释层、梯度、复合的概念十分重要,并对这些方法的原理进行了分析和探讨.要想获得理想的缓解残余应力的效果,发展多种方法相结合的复合缓解应力方法将是重要的研究方向.Abstract: Large residual thermal stress is usually formed within ceramic/metal joints because of the great mismatch in thermo-physical properties between the ceramic and metal to be joined.How to decrease the residual thermal stresses within the ceramic/metal joints has been always an important research branch in the field of ceramic (or ceramic matrix composite) joining.Seven methods for decreasing residual thermal stresses are summarized based on the worldwide research results in decades, in which the conceptions of buffer layer,gradient and composite are very important,and their mechanisms are analyzed.In order to achieve better effect,the authors suggest that different methods for decreasing residual thermal stresses should be combined with each other,and it would be an interesting research area.
