NICKEL BASE SOLDER Russian patent published in 2002 - IPC

FIELD: solder composition that may be used in machine engineering for making soldered parts and assemblies of gas turbine engines of aircrafts, ships and power plants, possibly for restoration of parts of gas turbine engines operating at high temperature. SUBSTANCE: nickel base solder contains, mas.%: silicon, 3.0-6.3; boron, 1.5-2.4; chrome, 2.5-8.0; aluminium, 0.5-4.0; niobium, 0.5- 4.5; tungsten, 0.3-0.5; nickel, the balance. EFFECT: lowered tendency of solder to intergrain penetration into alloys, reduced erosion capability of solder, enhanced heat resistance of soldered joints. 2 tbl
