| 摘 要： | In this study, Noeolok eutectic flux, used widely in the process of the brazing of aluminum and its alloy, was prepared by the reaction between AI(OH)3/KOH resolution and HF. A series of KF-A1F3 euteetic productions at various reaction temperatures were prepared. The melting points of the products were measured by differential thermal analysis (DTA), and the composites were characterized by X-ray diffraction (XRD).The results suggest that the temperature control is important to produce an ideal flux consisting of K2A1F5 , H2O and KA1F4 , with a low melting point of 560 ℃ ,which is suitable for the brazing of aluminum and its alloy as the aluminum fluxes. |

| Abstract: | In this study, Nocolok eutectic flux,used widely in the process of the brazing of aluminum and its alloy, was prepared by the reaction between Al(OH)3/KOH resolution and HF. A series of KF-AlF3 eutectic productions at various reaction temperatures were prepared. The melting points of the products were measured by differential thermal analysis (DTA), and the composites were characterized by X-ray diffraction (XRD). The results suggest that the temperature control is important to produce an ideal flux consisting of K2AlF5, H2O and KAlF4, with a low melting point of 560 ℃,which is suitable for the brazing of aluminum and its alloy as the aluminum fluxes. |
