Material deposition method for repairing aeronautical components

A method for repairing an aeronautical component comprising a nickel-based alloy, the method comprising the following steps:

• a) performing surface preparation on a damaged portion of the component;
• and
• b) depositing a plurality of layers on the damaged portion of the component by cold spraying a powdered material by a non-oxidizing carrier gas,
• wherein
• the powdered material which is deposited is the same alloy as the nickel-based alloy comprised in the component to be repaired,
• deposition is performed with pressure conditions between 40 and 80 bar and temperature conditions between 85° and 1100° C. of the carrier gas, and
• step b) comprises:
• depositing an anchoring layer of the plurality of layers with first pressure and temperature conditions of the carrier gas;
• and
• depositing at least one growth layer of the plurality of layers on the anchoring layer with second pressure and temperature conditions of the carrier gas,
• wherein the first pressure and temperature conditions are different from the second pressure and temperature conditions, and
• wherein the second pressure and temperature conditions are 65-75 bar and 1000-1100° C.
