Abstract
A diffusion-brazing filler powder for a part made of a nickel-, cobalt- or iron-based alloy A comprising particles of a defined alloy material B having specific functional properties tailored to the area of application of said part. The particles are substantially spherical and carry, on their surfaces, in the form of incrustations, add-ons comprising at least one fluxing element taken from the group: boron and silicon, these encrusted add-ons also being present in a free state in said powder.
