Abstract
An amorphous braze foil () produced by a melt-spin process has an upper side and a lower side. The upper side and the lower side are thinly coated with a film of metallic Ni-based, Co-based, or Ni—Co-based braze powder () with a particle size in the nanometer range, wherein both the braze foil () and also the braze powder () additionally include grain boundary stabilizing elements as alloying elements. In addition, melting point depressants can be present in the braze foil or in the nano braze powder () in a commercially common quantity or with a considerably increased proportion. With the braze foil () coated in this manner, both the melting temperature of the braze material and also the probability of recrystallization are advantageously reduced when brazing in the adjacent base material ().
