重力分离SHS陶瓷涂层致密化的研究

Densification of Ceramic Layers Made by SHS G-T Process

用自蔓延铝热－重力分离法制备了氧化铝陶瓷内衬复合钢管，分析了陶瓷层中气孔形成的原因，研究了预热温度、化学成分、冷却方式对陶瓷涂层致密度的影响。

Ceramic lined Pipe has been produced by SHS gravitational separation\|thermit process. The effects of chemical composition and Breheating temperature and cooling methods on the relative density were studied. The cause of forming gas hole was discussed.
