Abstract

L’invention se rapporte à un procédé de traitement d’une pièce métallique en au moins un élément métallique choisi parmi l’aluminium, le titane, le magnésium et les alliages de ceux-ci en vue de conférer à la pièce une protection contre la corrosion et des propriétés d’adhérence vis-à-vis d’une composition de revêtement, ledit procédé comprenant successivement les étapes suivantes : a) une étape de formation sur la pièce d’un film organique par réduction d’au moins un sel d’aryldiazonium ; b) une étape de formation d’une couche d’oxyde sur la pièce issue de l’étape a) par soumission de celle-ci à une anodisation ou à une conversion chimique sans chrome hexavalent.The invention relates to a method of treating a metal part in at least one metal element chosen from aluminum, titanium, magnesium and the alloys thereof with a view to giving the part protection against corrosion. corrosion and adhesion properties with respect to a coating composition, said method comprising successively the following steps: a) a step of forming an organic film on the part by reduction of at least one salt of aryldiazonium; b) a step of forming an oxide layer on the part from step a) by subjecting it to anodization or chemical conversion without hexavalent chromium.
