The present invention relates to aqueous post-treatment compositions and an immersion and/or electrolytical process using said compositions for corrosion protection of metal and/or metal alloy surfaces. The aqueous post-treatment compositions comprise at least one polysiloxane betaine compound and optionally at least one phosphorus containing compound. La présente invention concerne des compositions aqueuses de post-traitement et un procédé d'immersion et/ou électrolytique qui utilise lesdites compositions pour protéger des surfaces métalliques et/ou des surfaces d'alliage métallique contre la corrosion. Les compositions aqueuses post-traitement comprennent au moins un composé à base de bétaïne polysiloxane et éventuellement au moins un composé contenant du phosphore.
