| Abstract |
Al₂O₃ thick film was deposited into the steel pipe to increase the mechanical properties by thermit process. Al₂O₃ film was formed by exothermic reaction of Fe₃O₄ and Al powder. The porosity and the thickness of Al₂O₃ thick film were increased with increasing the Al₂O₃ content. However, the hardness of film is decreased with increasing the Al₂O₃ content as a heat adsorbent. Resulted in increasing of the thickness and the microhardness of the specimen. The increased compaction pressure of the forming. |
