NICKEL-BASED SOLDER Russian patent published in 2008 - IPC B23K35/30 C22C19/05 

FIELD: technological processes.

SUBSTANCE: solder has the following composition, mass %: chrome 7.0-9.5, silicon 0.3-0.7, boron 2.3-3.3, tungsten 8.0-11.5, aluminum 1.1-2.8, molybdenum 1.1-2.5, niobium 0.8-2.5, iron 0.4-1.7, carbon 0.05-0.15, cobalt 8.0-11.0, the rest is nickel. Solder application produces significant increase in welded junction durability, reduction welding defects and immense economical effect of prolonged gas-turbine engine life span.

EFFECT: increased heat resistance of compounds at longer welding exposition, and possibility to obtain amorphous solder strips.
