Yves Pauleau has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Multilayer material, anti-erosion and anti-abrasion coating incorporating said multilayer material
    Patent number: 5702829
    Abstract: The present invention relates to a multilayer material useful as an anti-erosion and anti-abrasion coating, and to a process for producing the multilayer material at low temperatures. The multilayer material comprises a substrate covered with at least one metallic tungsten ductile layer and at least one hard layer of a solid solution of an additional element chosen from carbon or nitrogen or a mixture of carbon and nitrogen in tungsten or a tungsten alloy, the two types of layers ar alternating. The multilayer material is particularly useful as a coating for parts used in aeronautics.

  • Multilayer material, anti-erosion and anti-abrasion coating incorporating said multilayer material and process for producing said multilayer material
    Patent number: 5547767
    Abstract: The present invention relates to a multilayer material more particularly intended for producing an anti-erosion and anti-abrasion coating, as well as the process for producing this multilayer material. The aim of the invention is to produce a material which has a greater resistance and which can be deposited at low temperatures. This aim is achieved with the aid of a multilayer material, which is characterized in that it comprises a substrate covered with at least one metallic tungsten ductile layer and at least one hard layer of a solid solution of an additional element chosen from among carbon or nitrogen or a mixture of carbon and nitrogen in tungsten or a tungsten alloy, the two types of layers are alternating. The invention more particularly relates to the production of a coating for parts used in aeronautics.
