Beschreibung
Zusammenfassung:	The invention relates to a method of manufacturing a coated spring, said method comprising the steps of - providing a steel wire; - coating said steel wire with a silane based coating in the range of 4 to 10 μm to provide a coated steel wire; - subjecting said coated steel wire to a mechanical deformation to obtain a coated and mechanical deformed steel wire; - subjecting said coated and mechanical deformed steel wire to a stress relief treatment. The invention further relates to a coated spring. L'invention concerne un procédé de fabrication d'un ressort revêtu, ledit procédé comprenant les étapes consistant à - utiliser un fil d'acier ; - revêtir ledit fil d'acier d'un revêtement à base de silane dans la plage de 4 à 10 µm pour créer un fil d'acier revêtu ; - soumettre ledit fil d'acier revêtu à une déformation mécanique afin d'obtenir un fil d'acier déformé mécaniquement et revêtu ; - soumettre ledit fil d'acier déformé mécaniquement et revêtu à un traitement de réduction des contraintes. L'invention concerne en outre un ressort revêtu.
