Abstract
In view of the fracture of sucker pipe due to the low toughness and low wear resistance, in order to prepare the ceramic-lined composite steel pipe with promising comprehensive performance, a self-propagating high-temperature synthesis (SHS) was explored to develop Al2O3-SiO2-ZrO2 system ceramic-lined steel pipe. The main phase of the ceramic layer is α-Al2O3, while FeAl2O4, Al2SiO5 and ZrO2 are present as minor phases, when the content of ZrO2 is in the range of 1-3 wt.%. Meanwhile, the crystal grain aspect ratio is significantly increased and the toughness is significantly enhanced. Steel/ceramics are composited through mechanical and diffusion mechanisms, with a interface compression shear strength of 10.46 MPa. With 2 wt.% SiO2 and 3 wt.% ZrO2, the relative density of the ceramics layer can be increased to 92.86%. In this case, the hardness can reach 1667 HV, the degree of wear can be reduced to 7.0 mg/h and the fracture toughness can reach 9.28
