Reducing the extent of interfacial reaction in Al matrix composite reinforced with SiC particles during remelt-recycling is critical to its commercialization and sustainable-development. In this article, the remelting behavior of the composite with SnO₂ coating on SiC particles during the remelting was investigated by Differential Scanning Calorimeter (DSC) and the thermodynamic calculations. The results showed that SnO₂ coating could reduce the reaction during remelting of composites, but the effect was not obvious with remelting time increasing. In addition, the equilibrium Si content was predicted from Wilson equation and the result of prediction was consistent with the experiment.
