    摘要: A method for repairing wider gaps in a substrate of a component by brazing at a brazing temperature is provided. Filler material and solder are prevented from separating in that, in a two-stage process, first the filler material and then the solder are applied to the wider gap. The powder does not melt at the brazing temperature and the filler metal does melt at the brazing temperature.

    摘要: A brazing composition for the brazing of superalloys including a base material with at least one initial phase is provided. The initial phase has a solidus temperature that is below the solidus temperature of the base material and, above a certain temperature, forms with the base material and/or with at least one further initial phase at least one resultant phase, the solidus temperature of which is higher that the solidus temperature of the initial phases. Heat treatment takes place in two stages, wherein the temperature of the second heat treatment is preferably 800-1200° C. The brazing composition may likewise be of the type MCrAlX, and the power particles of the initial phase may be in the form of nanoparticles.
