摘要对于许多不锈钢部件的大批量制造，通常首选使用保护气体炉的连续钎焊工艺。关于此处使用的镍基钎料的可加工性，在还原性或惰性保护气体中的炉内钎焊受到相当大的限制：一方面，最高钎焊温度受到特定工艺的限制，另一方面，由于待钎焊材料与工艺气氛的化学反应而产生的限制。因此，钎焊材料是改进工艺的重要起点。本文介绍了能满足连续保护气炉工艺条件的改性镍基钎料，并对改善用这种方法连接的不锈钢构件的性能提出了前景。
Abstract For high volume manufacturing of many stainless steel components, a continuous brazing process using a shielding gas furnace is usually preferred. Regarding the workability of the nickel-based brazes used here, furnace brazing in reducing or inert shielding gas is subject to considerable constraints: On the one hand, the maximum brazing temperatures are limited by the specific process and, on the other hand, limitations arise caused by the chemical reaction of the materials to be brazed with the process atmosphere. For this reason, the braze materials are an essential starting point for improving the process. In the present contribution, modified nickel-based brazes are introduced which meet the process conditions in continuous shielding gas furnaces and offer the prospect of improving the properties of stainless steel components joined in this way.
