| Abstract: |
| Combustion synthesis technology uses the energy released by chemical reaction efficiently. The aluminithermic reaction Fe_2O_3+Al-Fe+Al_2O_3 can produce melting products of Fe and Al_2O_3 which can be separated under centrifugal force to form ceramic--steel composite pipe. The main component of the ceramic layer is a--Al_2O_3, whose thickness is more than 2mm. The network structure of the ceramic layer improves its mechanical properties. The composite pipes have a great potential application in the field of resisting serious wear. Now, the pipes have been applied on an industrial scale in mines, power plants, and metallurgical industry. |
