Abstract
The aim of the invention is to provide a fluxing agent for soldering components, which creates one or more specific surface characteristics during the soldering process itself, thus obviating the need for the surface treatment process that is conventionally carried out after the soldering process. To achieve this, nanoparticles are added to a base substance.
Claims7
A process for brazing individual heat exchanger parts, comprising:
- adding starting materials for nanoparticles and an organic polymer to a base material prior to a brazing process;
- and
- depositing nanoparticles, which are formed by a chemical reaction during the brazing process, on a surface of the individual heat exchanger parts,
- wherein the organic polymer is configured to bind the nanoparticles and the base material.
