The Role of the Displacement Reaction in the Production of Surface Composite Layer

Abstract:

Composites of ceramic particle reinforcement (such as alumina) have potential for high temperature structural applications. In contrast to conventional processing methods (e.g. mechanical alloying), in situ processing techniques can be inexpensive and can also lead to unique microstructures, such as very fine dispersions of the reinforcements or interconnecting phases. The feasibility of processing Fe/Al₂O₃ composites layer by an in situ displacement reaction between Fe₂O₃ and Al by using laser beam pre-experiments were carried out and the results are presented in this paper.
