摘　　要：采用Al-Fe2O3-CrO3-Ti燃烧体系,制备出含有FeTi,FeCr,FeAl金属间化合物的金属过渡层与陶瓷层 双层复合结构的复合管。研究发现:利用金属间化合物作为梯度过渡层,使得基体与内衬层形成牢固的冶金结合, 提高了结合强度;同时,高硬度的金属过渡层与陶瓷层组成的双层复合结构使复合管的使用寿命和安全稳定性显 著提高。Based on self- propagating high- temperature synthesis （SHS） process of Al- Fe2O3- CrO3 -Ti system, a new type of composite pipe of double compound layer which was composed of FeTi,FeCr,FeAl intermetallic compound transition layer and ceramic layer was prepared. It was found that the intermetallic compound transition layer strengthened the metallurgy bonding of pipe and ceramic lining and improved the bonding strength. At the same time, double compound layer which was composed of metal transition layer with high hardness and ceramic layer improved the service life and safe stability of the composite pipes greatly.
