高温铝钎剂基本上可以分为:覆盖剂、去膜剂和界面活性剂三个组成部分。研究了15个不同组分和组成的覆盖剂,发现LiCl-SrCl_2,LiCl-NaCl-KCl与CaCl_2-NaCl-KCl依次为良好的覆盖剂体系,排除了碘化物和溴化物使用的现实性;去膜剂由含氟的化合物构成.详细筛选了周期系中所有可能用作界面活性剂的金属氯化物,研究了它们对纯铝、Al-Mg2.8和Al-Cu4.9-Mg1.8等铝合金的作用特性,发现TlCl对各种母材都有突出的活性作用。铝钎焊过程中钎剂失效主要是由于活性的液态金属层消失。ZnCl_2最易失效,而TlCl最不易失效。针剂中絮状物主要是由LiCl脱水过程中产生的水解产物OH~-所造成。提出了适用于不同铝合金的最佳钎剂组成。

Many reserchers have so far proposed that the active agents ofaluminum brazing fluxes are chlorides of heavy metal elements, however,this proposal seems to be not precise. In fact, most of the heavy metal chlo-rides could not be used as active agents. Moreover, the criterion of free energyfor standard formation of chlorides may only show that a substitution reactionwill must be thermodynamically possible in positive direction; nevertheless, it can show that a chloride must be useful as an acgents. The investigationshows, if the components are capable of forming two--liquid layers withaluminum in liquid state, or they are miscible with aluminum in liquid andthe formed eutectics have lower melting points at the non--aluminum side ofthe binary phase diagrams, then the chlorides of these components couldprincipally be used as active agents of aluminum brazing fluxes.

本文指出长期以来,众多研究者一直提到的铝钎剂的活性剂是重金属氯化物的说法是不够确切的。实际上,大多数重金属氯化物不能作为活性剂。同时指出氯化物标准生成自由能判据,仅仅表明取代反应能否正向进行,而不能说明该氯化物是否可以作为活性剂。本研究提出:液态时与铝形成双液层的组元,或者液态时与铝能互相溶解,但在二元合金状态图的非铝端,形成熔点较低共晶物的组元,这些组元的氯化物,原则上可以作铝钎剂的活性剂。

A new type of non-corrosive brazing flux has been studied. It shows that the new type of non-corrosive aluminum brazing flux, comparing with the chloride salt flux, has many advantages, moisture absorption free , long active time , producing sound brazing joint and without the need of postbraze cleaning. Comparing with fluoride eutectic fluxes, it possesses the advantages as : low melting temperature, good wetting ability, easy to prepare, etc.
