Patent ID: 8881965

Claim:
A Ni-based, Co-based, or Ni—Co-based brazing mixture for high-temperature brazing, the brazing mixture comprising: a first metallic powder component including particles with sizes in the nanometer range; a second metallic powder component including particles with sizes in the micrometer range; wherein a surface of the particles of the second powder component is coated with particles of the first powder component; at least one grain boundary stabilizing element as an alloying element of the first and of the second metallic powder components; wherein the first powder component and the second powder component comprise boron from about 3 to 7% by weight as a melting point depressant; and wherein the brazing mixture includes filler particles having a particle size in the range of 1-30 μm and a proportion in the overall brazing mixture of 1 to 40% by weight.
