Description

  

  Procédé pour rendre inoxydables des ressorts de mouvements d'horlogerie,  notamment des ressorts de barillets.    L'invention concerne un procédé pour  rendre inoxydables et partant     inrouillables,     des ressorts de mouvements d'horlogerie, no  tamment des ressorts de barillets de montres.  



  Dans les régions tropicales et intertropi  cales, les parties et organes en métal oxy  dable des montres et autres instruments de  précision analogues sont plus particulièrement  exposés à l'oxydation, ce qui est notamment  le cas pour les spiraux, ressorts de barillets  et autres ressorts-moteurs.  



  Pour obvier à cet inconvénient, les res  sorts en acier trempé sont recouverts, selon  l'invention, d'une     mince    couche métallique  pratiquement inoxydable et partant in  rouillable, formée de     préférence    par des  moyens galvanoplastiques.    Cette couche métallique de revêtement  inoxydable, par exemple un dépôt électroly  tique, peut être en nickel, chrome, argent ou,  dans des cas exceptionnels, en or. Toutefois,       ce    revêtement métallique pourrait consister  en une mince pellicule en métal     inrouillable     formée sur le ressort par des moyens autres  que galvanoplastiques, par exemple par im  mersion du ressort dans une     solution.  



  Process for rendering watch movement springs stainless steel, in particular barrel springs. The invention relates to a method for making watch movement springs, in particular watch barrel springs, rustproof and hence rustproof.



  In tropical and intertropical regions, the oxidizable metal parts and components of watches and other similar precision instruments are more particularly exposed to oxidation, which is particularly the case for balance springs, barrel springs and other springs. engines.



  To obviate this drawback, the hardened steel spells are covered, according to the invention, with a thin metal layer which is practically stainless and therefore rustproof, preferably formed by electroplating means. This metallic layer of stainless coating, for example an electrolytic deposit, can be made of nickel, chromium, silver or, in exceptional cases, gold. However, this metallic coating could consist of a thin film of rustproof metal formed on the spring by means other than electroplating, for example by immersing the spring in a solution.
