解决钢管和陶瓷层膨胀系数的不匹配问题是采用燃烧合成法（即铝热－离心法）制备陶瓷复合钢管技术的关键。降低反应温度，缓解了这一矛盾，但降低了产品质量．陶瓷层的网状结构消除了膨胀系数不匹配的后果，陶瓷层不再崩裂、剥落改善陶瓷层组织结构。特别是宏观结构，是稳定和提高产品质量的有效方法． Solve the pipe and ceramic layer expansion coefficient of the mismatch problem is the use of combustion synthesis (ie, aluminum heat - centrifugal method) Preparation of ceramic composite pipe technology key. Reduce the reaction temperature to alleviate this conflict, but reduced product quality. The mesh structure of the ceramic layer eliminates the consequence of the mismatch in the coefficient of expansion, the ceramic layer no longer cracks, and the exfoliation improves the microstructure of the ceramic layer. In particular, the macro structure, is an effective way to stabilize and improve product quality.
