Abstract

A ceramic-lined composite steel pipe (CLCSP) was fabricated with N80 steel tube as substrate by self-propagating high-temperature synthesis and centrifugal casting technique. The constituent phases and microstructure of the ceramic layer were analyzed, and the mechanical properties of CLCSP were measured, including hardness, crashing strength, compression-shear strength and tensile performance. The wear and corrosion behaviors between CLCSP and N80 steel tube were also compared. The results show that ceramic layer consists of columnar dendrites of Al2O3 and spinel-like structure FeAl2O4, CLCSP has a much higher hardness, squeezing deformation resistance, wear and corrosion resistance as compared with N80 steel tube.
