| Abstract: | The ceramic lined pipe has been produced by centrifugal process of self propagating & high temperature synthesis(SHS). The effects of the diluents on density, microstructure and hardness of ceramic lined are investigated. The results show that the microstructure and hardness of ceramic lined are different and the grains are of cylinder or axialite with adding of different diluents. The density and porosity are improved by increasing the centrifugal force or by expanding the cooling time with adding diluents. |
