【摘要】 在离心力的作用下，采用自蔓延高温合成技术（ＳＨＳ）制备复合金属管，研究添加剂对内衬层致密度、显微结构和显微硬度的影响．实验得出，反应物中加入添加剂，内衬层的显微结构不同，陶瓷晶粒呈柱状晶或等轴晶，并且内衬层显微硬度两相不均．通过增加离心力或添加能延长熔融期的添加剂，可改善内衬层的致密度，减少气孔．更多还原

【Abstract】 The ceramic lined pipe has been produced by centrifugal process of self propagating & high temperature synthesis(SHS). The effects of the diluents on density, microstructure and hardness of ceramic lined are investigated. The results show that the microstructure and hardness of ceramic lined are different and the grains are of cylinder or axialite with adding of different diluents. The density and porosity are improved by increasing the centrifugal force or by expanding the cooling time with adding diluents.更多还原
