Abstract
Describes a novel method for composite brazing,
consisting of the application of multilayer composite brazing alloys of the
Cr–Ni–Mn system in the form of coatings with efficient alloying of the brazed
surfaces with chromium and the production of joints with an optimum thickness
smaller than 80 μm.
The technology can be used to produce
high-quality joints at the temperature of optimum heat treatment of steels,
prevent clogging of cooling channels with a small cross section, increase the
chromium content of the joint to a level similar to the chromium content of
steels, produce corrosion-resisting joints with a strength equal to that of
12Cr18Ni10Ti steel and reduce the weight of the component by 30%.
