Title
(EN) METHOD TO IMMOBILIZE AN ENTRAPPED CONTAMINANT WITHIN A HONEYCOMB STRUCTURE
(FR) PROCÉDÉ POUR IMMOBILISER UN CONTAMINANT PIÉGÉ À L'INTÉRIEUR D'UNE STRUCTURE EN NID D'ABEILLES
Abstract
(EN) A method of immobilizing a contaminant within a component includes identifying the contaminate; and thermally processing the component via a specific thermal cycle related to the contaminate. A method of repairing a component includes immobilizing a contaminant within the component; and weld repairing the component subsequent to immobilizing the contaminant. An aerospace component includes a honeycomb structure with a thermally decomposed contaminate and a weld repair.
(FR) L'invention concerne un procédé d'immobilisation d'un contaminant à l'intérieur d'un composant, comprenant l'identification de la contamination; et le traitement thermique du composant par l'intermédiaire d'un cycle thermique spécifique se rapportant à la contamination. Un procédé de réparation d'un composant comprend l'immobilisation d'un contaminant à l'intérieur du composant; et la réparation par soudure du composant après immobilisation du contaminant. Un composant aérospatial comprend une structure en nid d'abeilles avec une contamination thermiquement décomposée et une réparation soudée.
