<p>PROBLEM TO BE SOLVED: To provide a powder used for a diffusion-brazing method. SOLUTION: A diffusion-brazing filler powder for a part made of a nickel-, cobalt- or iron-based alloy A, includes the powder comprising particles of a defined alloy material B having specified functional properties tailored to the area of application of the part. The particles are substantially spherical and carry, on their surfaces, in the form of incrustations, additions comprising at least one fluxing element selected from the group consisting of: boron and silicon. The material of the encrusted additions is also present in a free state in the powder.</p> |
