CA 2688655

The invention relates to a connection 1 between a first component and a second component, the first component being formed from an aluminium alloy in particular and the second component being formed from a carbon-fibre-reinforced plastics material in particular. The first component is a rib 6 in particular and the second component is preferably an angle bracket 7, with which the rib 6 is connected to an aircraft fuselage skin 2 within a fuselage reinforcement structure. The connection 1 between the components comprises, according to the invention, a ceramic coating 16 which is applied for protection against corrosion at least in the region of a contact area 9 between the components, the components being riveted and/or adhesively bonded. The ceramic coating 16 is less than 0.1 mm thick and may be formed from a mixture of aluminium oxide (AI2O3) and TiO2 for example.

La présente invention concerne un raccordement 1 entre un premier et un deuxième composant, le premier composant étant formé à partir d'un alliage d'aluminium en particulier et le deuxième composant étant formé à partir d'une matière plastique renforcée par des fibres de carbone en particulier. Le premier composant est une nervure 6 en particulier et le deuxième composant est de préférence une équerre de fixation 7 permettant de relier la nervure 6 à un revêtement de fuselage d'un avion 2 dans une structure de renfort du fuselage. Le raccordement 1 entre les composants comprend, selon l'invention, un revêtement céramique 16 appliqué au moins dans la région d'une zone de contact 9 entre les composants pour la protection contre la corrosion, les composants étant rivetés et/ou assemblés de manière adhésive. Le revêtement céramique 16 a une épaisseur inférieure à 0,1 mm et peut être formé à partir d'un mélange d'oxyde d'aluminium (AI2O3) et de TiO2 par exemple.
