摘要：

Aiming at ceramic-lined layered pipes employed under special conditions, layered structure of ceramic-lined pipes is redesigned by adding (TiO2+Al+C+Ni) subsystem with different contents in (CrO3+Al) main system, and the composite pipe with three-layer structure of steel substrate, the intermediate and ceramics is obtained. SEM images and EPMA analyses indicate that the intermediate is made of Cr-Ni-Fe-Al-Ti, in which Ti carbide particles or fine dendrites of Ti enrichment are embedded with graded distribution. Mechanical tests and SEM images show that as (TiO2+Al+C) subsystem and Ni metallic additive is up to 10% and 15% of whole combustion system respectively, compressive strength and compressive shear strength of the pipe simultaneously reach the maximum values.
