Abstract
L'invention concerne un composant mécanique (10) présentant un trou (12) traversant, et une épaisseur minimale (T) de 7 mm mesurée depuis une surface intérieure (12a, 12b) constituant le périmètre extérieur du trou (12) radialement vers l'extérieur jusqu'à une surface extérieure dudit composant mécanique (10). La dimension transversale maximale (d) dudit trou (12) est égale ou inférieure à 31,75 mm. Au moins une partie (22) du matériau de la surface intérieure (12a, 12b) du composant mécanique (10) constituant le périmètre extérieur dudit trou (12) comprend une microstructure martensitique obtenue par durcissement par induction au moyen d'une bobine d'induction électromagnétique (14) positionnée à l'intérieur dudit trou (12), suivi d'une trempe immédiate au moyen d'un dispositif de trempe (16) placé à l'intérieur dudit trou (12) après que la bobine d'induction électromagnétique (14) a été retirée dudit trou (12) ou pendant que la bobine d'induction électromagnétique (14) est retirée dudit trou (12).
