A noble metal tip (20) for attachment to a spark plug center electrode (36) and/or a ground electrode. Noble metal tip (20) is a generally cylindrical component that includes a firing end (40), an attachment end (42), and one or more retention features (44, 46 and 60, 62). The retention features are generally conically shaped holes or recesses formed in the side of the noble metal tip, and are designed to receive molten material during a laser attachment process. Once the molten material has solidified in the retention features, a fusion layer is formed and acts as a mechanical bond or interlock between the noble metal tip and the electrode. Methods of manufacturing and attaching the noble metal tips are also provided.

L'invention concerne une pointe (20) de métal noble destinée à être fixée à une éléctrode centrale (36) de bougie d'allumage et/ou une électrode de masse. La pointe (20) de métal noble est un composant généralement cylindrique comprenant une extrémité (40) d'allumage, une extrémité (42) de fixation, et un ou plusieurs éléments (44, 46, 60, 62) de retenue. Les éléments de retenue sont généralement des orifices ou des cavités de forme conique formés sur le côté de la pointe de métal noble, et sont destinés à recevoir un matériau fondu au cours d'un processus de fixation au laser. Lorsque le matériau fondu se solidifie dans les éléments de retenue, une couche de fusion est formée, formant une liaison ou un interverrouillage mécanique entre la pointe de métal noble et l'électrode. L'invention concerne également des procédé de fabrication et de fixation des pointes de métal noble.
