Abstract
A method for coating an annular inclined surface of a part with a powder prior to sintering, in which a lower annular axial surface is provided below and extending the inclined surface of the part. Along the axis of the part, a central tool is arranged having a lower axial surface slidable relative to the lower annular axial surface and an annular inclined surface above the lower axial surface and facing the annular inclined surface of the part. The part and the tool define an annular gap which is closed at the bottom portion and which has an open annular upper end above the annular inclined surface and the inclined surface of the part. The annular gap is filled with a powder through the open upper end which is then closed, and the part with the lower annular axial surface and the central tool are then relatively displaced, causing the inclined surface of the part and the annular inclined surface to become closer and compress the powder against the annular inclined surface of the part.
