A study of ceramic-lined composite steel pipes prepared by SHS centrifugal-thermite process
Al2O3 ceramic-lined steel pipe was produced by self-propagating high-temperature synthesis centrifugal thermite process (SHS C-T process) from Fe2O3 and Al as the raw materials. The composition, phase separation and microstructures were investigated. The result showed the ceramic lined pipe...

| Summary: | Al2O3 ceramic-lined steel pipe was produced by self-propagating
high-temperature synthesis centrifugal thermite process (SHS C-T process)
from Fe2O3 and Al as the raw materials. The composition, phase separation and
microstructures were investigated. The result showed the ceramic lined pipe
is composed of the three main layers of various compositions, which were
subsequently determined to be Fe layer, the transition layer and the ceramic
layer. Fe layer is composed of austenite and ferrite, the transition layer
consisted of Al2O3 ceramic and Fe, the ceramic layer consisted of the
dendritic-shaped Al2O3 and the spinel-shaped structured FeAl2O4. |
