采用自蔓延铝热-熔覆法制备陶瓷内衬复合钢管，这种复合钢管具有良好的综合性能。研究了陶瓷层与钢管的结合机理和陶瓷层的相结构。通过对Al-Fe2O3系自蔓延燃烧过程的分析得知，扩散燃烧机制为反应过程的主要作用机制。
The self-propagating aluminum heat-cladding method is adopted to prepare the ceramic lined composite steel pipe, and the composite steel pipe has good comprehensive performance. The bonding mechanism between ceramic layer and steel tube and the phase structure of ceramic layer were studied. Through the analysis of Al-Fe2O3 self-propagating combustion process, diffusion combustion mechanism is the main mechanism of the reaction process.
