就铝用氟化物钎剂的不同配制方法进行了对比,测定了各种方法配制的钎剂组成,分析了配制机理,并对制取的钎剂进行了钎焊性能的测定.测定结果表明,四种钎剂的钎焊性能无多大差别.认为水调法、水煮法制取针剂方法简单,更适于生产. In this paper, we compared the preparation methods of aluminum fluoride fluxes, measured the composition of the fluxes prepared by various methods, analyzed the preparation mechanism, and measured the brazing properties of the prepared fluxes.The results show that, There is not much difference in the brazing performance of the four fluxes, which is that the water-adjusting method and boiling method are simple and suitable for production.
