Abstract

L'invention concerne un procédé de désolidarisation d'une première pièce mécanique (12) d'une deuxième pièce mécanique (14), la deuxième pièce mécanique (14) étant collée à la première pièce mécanique (12) par un film de colle (16) selon une zone de liaison, la première pièce mécanique (12) étant d'une première conductivité thermique déterminée et la deuxième pièce mécanique (14) étant d'une deuxième conductivité thermique supérieure à la première conductivité thermique, caractérisé en ce qu'il comporte au moins une étape de refroidissement au cours de laquelle on refroidit la deuxième pièce mécanique (14) à une température négative et au moins une étape de sollicitation au cours de laquelle on soumet la deuxième pièce mécanique (14) à une sollicitation mécanique pour provoquer la rupture du film de colle (16).
