Corrosion resistance of Zn–Ni/Ni and Ni/Zn–Ni compositionally modulated multilayer coating / J.-L. Chen in Materials and corrosion, Vol. 63 N° 7 (Juillet 2012) 

Public ISBD [article]  in Materials and corrosion > Vol. 63 N° 7 (Juillet 2012) . - pp. 607–613 Titre : Corrosion resistance of Zn–Ni/Ni and Ni/Zn–Ni compositionally modulated multilayer coating Type de document : texte imprimé Auteurs : J.-L. Chen, Auteur ; J. H. Liu, Auteur ; S. M. Li, Auteur Année de publication : 2012 Article en page(s) : pp. 607–613 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Corrosion  resistance;  multilayer;  Ni;  Zn–Ni  alloy Résumé : Zn–Ni/Ni and Ni/Zn–Ni compositionally modulated multilayer (CMM) coatings were prepared by dual-bath technique. The effects of layers number and sublayers order were studied. Specially, the effect of different sublayers thickness ratios with the same multilayer period (λ) on the corrosion resistance of the CMM coatings was investigated in detail. Results showed that the corrosion resistance of Ni/Zn–Ni (Zn–Ni alloy sublayer as the top layer) CMM coating was better than that of Zn–Ni/Ni (Ni sublayer as the top layer) CMM coating. The 6-layer CMM coating with the layer thickness ratio of Ni/Zn–Ni = 0.8:1.2 (λ = 2 µm) has the best corrosion resistance.
