| Abstract: | Using self-propagating high temperature synthesis(SHS)process and centrifugal technique,ceramic-ling compound steel pipes has been fabricated,principles of SHS ceramic-ling compound steel pipes are analyzed and the properties of compound steel pipes are measured,The ceramic layers of compound steel pipes have high hardness and good wear resistance,but its porosity is very high and its toughness is very low, the compactability of ceramic is increased and corrosive resistance is improved by adding SiO2 in thermite,can increased fracture toughness of ceramic by adding ZrO2. Its application resultes. are very good in slurry transportation pipe lines. |
