MUMBAI, India, June 26 -- Intellectual Property India has published a patent application (202617067573 A) filed by Safran Helicopter Engines on May 29, 2026, for Method For Completing The Finishing Of A Component Produced By Depositing And Solidifying Successive Layers Of A Powder, And Component Obtained By This Method.
Inventors include Lagrange, Sandrine Marie Jeanine; and Ithurritca, Isabelle.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: A method for completing the finishing of a component produced by depositing and solidifying successive layers of a powder, characterized in that it comprises: - a rough-finishing step (E1) involving sandblasting a part of a surface of the component having an initial roughness (Ra0) using a first sand (S1) having a rough-finishing particle size (G1) and blasted at a rough-finishing sandblasting angle (A1) and a rough-finishing sandblasting pressure (P1) until the part of the surface of the component attains a rough-finished roughness (Ra1), and - a finishing step (E2, E2') of finishing the part of the surface of the component until the part of the surface of the component attains a final roughness (Ra2), where the final roughness (Ra2) is lower than the rough-finished roughness (Ra1).
