TITANIUM-BASED SOLDER FOR SOLDERING ALLOY BASED ON NIOBIUM INTERMETALLIDE Russian patent published in 2016 - IPC B23K35/30 C22C14/00

Abstract RU 2600785 C1

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, specifically to high-temperature solder based on titanium, which can be used in making soldered components of hot section of gas turbine engines. Titanium-based solder for soldering niobium intermetallide-based alloy with melting point not lower than 1,350 °C contains wt%: aluminium 18.0-25.0, molybdenum 1.0-10.0, silicon 3.0-6.0, chrome 10.0-15.0, hafnium 1.0-5.0, titanium - balance.

EFFECT: solder provides additional weight at temperature 1,350 °C higher than that of niobium intermetallide-based alloy, and value of erosion activity with respect to niobium intermetallide-based alloy not more than 50 mcm at a temperature of 1,500 °C.
