摘要

采用重力分离SHS技术制备双衬陶瓷复合管

双衬陶瓷间因出现Al2 O3 基体和（Al2 O3 +FeO·Al2 O3 ）共晶组织的重熔区使双衬陶瓷间出现局部冶金结合方式

使得双衬陶瓷裂纹密度下降。第二衬陶瓷层的相对密度和硬度比第一衬陶瓷层均有所提高

但双衬陶瓷层间抗压剪强度和双衬陶瓷复合管的抗压溃强度比钢管与陶瓷层间抗压剪强度及单衬陶瓷复合管的抗压溃强度均有所下降。

Abstract

Bi-lined ceramic composite pipes are fabricated by gravitational separation SHS technology. Occurrence of remelted area of Al\-2O\-3 matrix and （Al\-2O\-3 + FeO·Al\-2O\-3） eutectic between bi-lined ceramics make them bond with partial metallurgical pattern

resulting in crack density reduction of each lined ceramics. Relative density and hardness of second lined ceramics layer increased more than those of the first lined ceramics layer

but compressive shear strength between bi-lined ceramics layer as well as compressive strength of bi-lined ceramic pipes are decreased more than those between ceramics and steel pipe as well as of single lined ceramic pipes.
