Title
(EN) IMPROVED PRE-TREATMENT PROCESS OF A SURFACE OF A METALLIC SUBSTRATE
(FR) PROCÉDÉ DE PRÉTRAITEMENT AMÉLIORÉ D'UNE SURFACE D'UN SUBSTRAT MÉTALLIQUE
Abstract
(EN)
Process for pre-treatment of a surface of a chromium containing corrosion resistant metallic substrate prior to further processing, wherein the metallic substrate is brought into contact with an in-situ generated activating agent, being the thermal decomposition product of a hydrofluoroolefin, the substrate and the activating agent are heated, and optionally the activating agent is partly or entirely removed before further processing.
(FR)
L'invention concerne un procédé de prétraitement d'une surface d'un substrat métallique résistant à la corrosion contenant du chrome avant un traitement ultérieur, le substrat métallique étant mis en contact avec un agent d'activation généré in situ, étant le produit de décomposition thermique d'une hydrofluoroléfine, le substrat et l'agent d'activation étant chauffés, et éventuellement l'agent d'activation étant partiellement ou entièrement retiré avant un traitement ultérieur.
