1\u3001 Nature diff\u00e9rente
\n1. D\u00e9capage : une m\u00e9thode de nettoyage des oxydes et de la rouille sur les surfaces m\u00e9talliques avec une solution acide
\n2. Passivation : le processus dans lequel un m\u00e9tal est oxyd\u00e9 par un oxydant fort ou une m\u00e9thode \u00e9lectrochimique pour rendre sa surface inactive, c'est-\u00e0-dire passive.<\/p>\n
2\u3001 Diff\u00e9rents principes
\n1. D\u00e9capage : D'une mani\u00e8re g\u00e9n\u00e9rale, les pi\u00e8ces sont immerg\u00e9es dans certaines solutions aqueuses acides telles que l'acide sulfurique pour \u00e9liminer les oxydes ou autres films \u00e0 sa surface. C'est le processus de pr\u00e9paration des pi\u00e8ces m\u00e9talliques avant tout autre traitement de surface (tel que le placage) ou l'\u00e9tape interm\u00e9diaire du traitement de surface.
\n2. Passivation\u00a0: apr\u00e8s la formation d'une couche de film d'oxyde ou d'hydroxyde sur la surface du m\u00e9tal, l'augmentation de la tension appliqu\u00e9e n'affecte pas le courant, la dissolution des ions m\u00e9talliques est arr\u00eat\u00e9e et il a une r\u00e9sistance \u00e0 la corrosion.<\/p>\n

\n2. Passivation : avant le d\u00e9capage et la passivation des pi\u00e8ces m\u00e9talliques, v\u00e9rifiez si leurs surfaces sont propres. S'il y a des taches ou de la graisse, elles doivent \u00eatre nettoy\u00e9es m\u00e9caniquement avec les solvants organiques correspondants. Parce que les taches et la graisse sur la surface affecteront la qualit\u00e9 du d\u00e9capage et de la passivation.<\/p>\n
Il est important de s\u00e9lectionner le processus de traitement de surface appropri\u00e9 pour les pi\u00e8ces personnalis\u00e9es, ce qui affectera non seulement l'effet global du produit, mais affectera \u00e9galement le co\u00fbt du projet. Ainsi, les ing\u00e9nieurs professionnels peuvent vous fournir des connaissances correctes et efficaces.<\/p>","protected":false},"excerpt":{"rendered":"
