Abstract
L'invention vise à améliorer les propriétés d'utilisation et la méthode de fabrication d'une électrode centrale de bougie d'allumage, dans laquelle une pointe filiforme, composée d'un matériau résistant à l'usure et très résistant à la corrosion, est prévue sur le corps de base de l'électrode. Selon la présente invention, la pointe de bougie est représentée par la section libre d'un fil sous gaine (4) en saillie sur le corps de base (1), la gaine, composée d'un matériau doté de bonnes propriétés de soudage, d'une résistance suffisante à la corrosion et d'une résistance mécanique élevée, étant reliée à une ame composée d'un matériau résistant à l'usure et très résistant à la corrosion.The invention aims to improve the properties of use and the method of manufacturing a central spark plug electrode, in which a threadlike tip, composed of a material resistant to wear and very resistant to corrosion, is provided on the base body of the electrode. According to the present invention, the spark plug tip is represented by the free section of a sheathed wire (4) projecting from the base body (1), the sheath, composed of a material endowed with good welding properties, with sufficient corrosion resistance and high mechanical resistance, being connected to a core made of a material resistant to wear and very resistant to corrosion.
