尽管活性填充合金用于钎焊陶瓷的应用领域广泛，并且在过去的几十年中对这些合金在陶瓷表面的润湿和扩散行为进行了大量的研究，但由于合金对钎焊条件的高度敏感性，制造的接头仍然表现出显着的性能变化。这增加了研究填充合金润湿和扩散行为的需要，考虑到主要影响因素及其相互依赖性，而不是仅仅关注单一参数的研究。为此，在SiC衬底上对凝固后的AgCuTi和CuSnTi合金进行了润湿角和润湿面积的测量。基于这些测量结果，建立了一个回归模型，说明了钎焊温度、烧结表面粗糙度、炉内气氛及其相互关系对钎料合金润湿和扩散行为的影响。结果表明，熔体的行为受到不同钎焊参数及其相互依赖关系的显著影响。所建立的模型对这一结果进行了预测，并显示出较高的精度。
Despite the broad field of applications for active filler alloys for brazing ceramics, as well as intense research work on the wetting and spreading behavior of these alloys on ceramic surfaces within the last decades, the manufactured joints still exhibit significant variations in their properties due to the high sensitivity of the alloys to changing brazing conditions. This increases the need for investigations of the wetting and spreading behavior of filler alloys with regard to the dominating influences combined with their interdependencies, instead of solely focusing on single parameter investigations. In this regard, measurements of the wetting angle and area were conducted at solidified AgCuTi and CuSnTi alloys on SiC substrates. Based on these measurements, a regression model was generated, illustrating the influence of the brazing temperature, the roughness of the faying surfaces, the furnace atmosphere, and their interdependencies on the wetting and spreading behavior of the filler alloys. It was revealed that the behavior of the melts was significantly influenced by the varied brazing parameters, as well as by their interdependencies. This result was also predicted by the developed model and showed a high accuracy.
