The wear resistant conveying pipeline consists of an aluminum oxide (AL2O3) layer, binder, and a steel pipe layer from the inside out. The alumina ceramic layer is formed at high temperatures above 1600 ° C and forms a strong metallurgical bond with the steel pipe and binder. It has good corrosion resistance, wear resistance, high strength, toughness, and strong resistance to mechanical and thermal impacts. Overall performance. And it can perform machining such as turning, grinding, welding, etc. So far, no composite material has such excellent comprehensive performance.
