  • METHOD FOR JOINING, BY DIRECT BRAZING, A FIRST PART AND A SECOND PART, INCLUDING STEPS OF PREPARING THE SURFACE OF AT LEAST ONE OF THE PARTS
    Publication number: 20240075546
    Abstract: A method for joining, by brazing, a first part and a second part, the steps of preparing at least one of the parts including the following: a) providing a part intended to be brazed, the part being made of carbon or based on titanium, nickel or a CoCr alloy, b) performing inert gas plasma treatment on the part whereby the part is cleaned and an active surface is formed on the part, c) depositing a first layer comprising an active element on the active surface of the part, the active element being a carbide-forming element, d) depositing a second layer of gold on the first layer, whereby the first layer is protected from oxidation and good wetting is ensured.

  • Annular sintered magnet with radial magnetization and reinforced mechanical strength
    Patent number: 9748030
    Abstract: A sintered annular magnet with a radial orientation of a remanent magnetic field, including: a principal annular part made from a ferromagnetic material, that has a first degree of magnetic anisotropy in the radial direction; and an annular reinforcing part fixed to the principal part of the magnet, the reinforcing part being made from same ferromagnetic material as the ferromagnetic material forming the principal part, and that has a second degree of magnetic anisotropy in the radial direction, the first degree being higher than the second degree.
