NICKEL BASED SOLDER Russian patent published in 2010 - IPC B23K35/30

Abstract RU 2393074 C1

FIELD: chemistry.

SUBSTANCE: invention can be used in making components from deformed or cast heat-resistant nickel alloys, particularly for hot section of gas turbine engines such as compressor stators and turbine nozzle assemblies. The solder has the following composition in wt %: Cr 10.0-20.0, Fe 0.06-0.18, Mo 1.5-6.0, Co 2.5-6.5, Nb 1.5-4.0, Si 2.8-6.0, B 1.5-2.5, Ti 0.2-0.5, Mn 0.8-1.0, Al 0.2-0.5, C 0.01-0.2, Ni - the rest.

EFFECT: use of the disclosed solder increases reliability of solder joints due to increase in heat resistance of the joints at temperature of up to 800°C and its low erosion activity.
