摘　　要：采用重力分离 SHS法制备了大直径钢管陶瓷内衬 ,研究了物料配比和添加剂 ( Si O2 和 Cr O3 )对于 SHS合成过程和组织结构的影响 .实验表明 ,用适当的物料配比 ,加入一定的添加剂 ,可以改善陶瓷层的组织结构 ,使其与基体实现很好的结合 .The method for producing big diameter metal pipes with ceramic lining by gravitational separation SHS method is described. The influence of the reactant and additives CrO 3 and SiO 2 on combustion synthesis, microstructure and properties of the ceramic layer is investigated. The results of the experiments show that the microstructure of ceramic layers can be improved by choosing suitable proportions of reactants and additives.
