Abstract

Procédé non destructif de contrôle et de caractérisation, in situ et en temps réel de l’homogénéité de pièces métalliques fabriquées par frittage laser L’invention concerne un procédé de fabrication d’une pièce métallique par frittage laser et de caractérisation in-situ et non destructive de la pièce métallique, comprenant les étapes suivantes : (a) formation d’au moins une couche (C) de la pièce métallique par frittage laser, comprenant l’émission par un dispositif laser (3) d’au moins un faisceau laser (9a-b) sur un lit de poudre (P) du matériau constitutif de la couche ; (b) émission d’au moins un faisceau laser (14a-c) par le même dispositif laser ayant servi au frittage laser selon l’étape (a), de sorte à irradier et par-là chauffer au moins une partie de la surface de la couche formée, afin d’en réaliser sa caractérisation par radiométrie photothermique modulée à détection synchrone. Figure pour l’abrégé : Fig. 2
