Abstract
Procédé et appareil de détection de fragments de substrat usiné par thermographie. Une source thermique applique de la chaleur à une surface dun composant usiné, la surface donnant accès à une ou à plusieurs chambres internes dun espace intérieur du composant. Lapplication de chaleur est suffisante (en température et en durée) pour créer un taux délévation de température de fragment dans au moins un fragment de substrat usiné présent dans au moins une chambre interne qui est supérieur au taux délévation de température du composant. Un dispositif de détection infrarouge en communication fonctionnelle avec un dispositif de sortie visuelle capte le signal infrarouge de la surface du composant après lapplication de chaleur et émet une image thermique du composant. Les points délévation de chaleur, dans limage thermique, correspondent à la présence de fragments de substrat usiné dans au moins une chambre interne du composant.
