Effect of La_2O_3, Y_2O_3 Additives on Structure and Mechanical Property of Ceramic-Lined Composite Pipe Under Centrifugation

摘要

The effect of additives containing rare earth elements La and Y on the structure and mechanical property of ceramic-lined composite pipe was studied in presence of centrifugation. The fracture and shearing strength of ceramic-lined composite pipe containing different additives were measured and analyzed through the fracture and shearing strength experiments. The distribution of shear stress on the interface of ceramic layer and the pipe is computed by finite element method.
