  • Method for producing a nickel aluminide coating on a metal substrate, and part having one such coating
    Patent number: 10549378
    Abstract: The invention relates to a method for producing a nickel aluminide coating on a metal substrate. The method includes the following steps: a) coating the substrate with a nickel deposit; b) applying an aluminum sheet onto the nickel deposit from step a) so as to form an assembly made up of the substrate coated with the nickel deposit and the aluminum sheet; and c) subjecting said assembly to heat treatment at a temperature that is lower than the melting point of aluminum, and at a low pressure so as to induce a reaction between the aluminum and the nickel and thus form a ?-NiAl nickel aluminide layer mounted on a nickel layer. The invention is particularly of use for protecting the materials used in turbines of aircraft engines.

  • Method of surface marking a mechanical part with a predefined graphical representation visible to the naked eye
    Patent number: 10138170
    Abstract: The invention relates to a method of surface marking a mechanical part with a predefined graphical representation, the method comprising using a laser source to apply a single laser pulse to an outside surface of a part for marking, with a mask being interposed between the laser source and the outside surface of the part, the mask having a predefined graphical representation, and the laser pulse having power flux density of at least 20 MW/cm2 and a duration less than or equal to 100 ns.

  • Method for Producing a Nickel Aluminide Coating on a Metal Substrate, and Part having One Such Coating
    Publication number: 20150056467
    Abstract: The invention relates to a method for producing a nickel aluminide coating on a metal substrate. Said method includes the following steps: a) coating the substrate with a nickel deposit; b) applying an aluminum sheet onto the nickel deposit from step a) so as to form an assembly made up of the substrate coated with the nickel deposit and the aluminum sheet; and c) subjecting said assembly to heat treatment at a temperature that is lower than the melting point of aluminum, and at a low pressure so as to induce a reaction between the aluminum and the nickel and thus form a ?-NiAl nickel aluminide layer mounted on a nickel layer. The invention is particularly of use for protecting the materials used in turbines of aircraft engines.
