PROBLEM TO BE SOLVED: To provide a new brazing composition for use with a nickel-based superalloy. A nickel-based braze composition containing nickel, palladium, and limited amounts of boron and silicon is described. The composition can further contain tantalum, titanium and zirconium, and aluminum, chromium and cobalt. A method of joining two metal parts using this braze composition is also described. The braze composition can also be used to fill cracks or other cavities in parts such as, for example, gas turbine parts formed from nickel-based superalloys. An article of manufacture comprising a wax composition is also described. |
