摘要
To improve the reaction efficiency of aluminum in the Al/Mg alloy with water, the surface coating of Al/Mg alloy powder was performed with fluoride. The reaction products of the alloy powders with high temperature water were characterized by scanning electron microscopy(SEM), X-ray diffraction (XRD) and laser particle size analyzer. The effect of different proportions of fluoride on the catalytic reaction efficiency of Al/Mg alloy with water at high temperature was compared and studied. The results show that the particle size of reaction products of Al/Mg alloy coated fluorides decrease and the dispersity was obviously improved. The combustion products in solid state mainly include MgO, Al2MgO4 and Al, meaning that Al does not react completely. The reaction efficiency of aluminum in alloy powder coating with fluorides was significantly improved, in which, the reaction efficiency of alloy powder coating with 2% Viton and 2% organic fluoride is up to 89.7%, which is 14.6% higher than that of the uncoated sample.
