Latest Patents

Didier Perraud holds a patent for a method of making a deposit on a component made of a nickel or cobalt-based superalloy. This method involves depositing a material consisting of reactive powders or superalloy powder onto the component. The component is then placed in a chamber where it is subjected to a neutral gas at a hydrostatic pressure of up to 1.5 GPa. The chamber is equipped with heating means to control the temperature up to 1200°C, with a specific rate of increase and thermal gradient. The conditions in the chamber are designed to facilitate a synthesis reaction by self-propagated combustion under high pressure, resulting in densification of the deposit and metallurgical bonding with the component.
