“…5, SiC nanoparticles did not distribute in the oxide film homogeneously, but preferentially rested in the holes, crevices and sidewalls of protuberances. Similar phenomena were observed by Mu et al [6,11,17,21,24]. It was probably associated with the bonding forces between the oxide film and nanoparticles.…”

“…It was interesting to find that SiC nanoparticles did not distribute in the oxide films homogeneously and a significant fraction of nanoparticles were embedded preferentially in the holes, crevices and sidewalls of protuberances. The bonding energy needed for the SiC nanoparticles to deposit in the holes, crevices or sidewalls of protuberances was lower than on the flat positions [24]. Moreover, the mechanical entrapment of holes, crevices and sidewalls of protuberances was contributed to the deposition of SiC nanoparticles in the oxide film as well [11].…”

Pure zinc and Zn-MoS 2 composite coatings were prepared by electrodeposition from zinc sulfate-chloride bath containing uniformly dispersed MoS 2 nanoparticles. The effect of MoS 2 on the deposition properties morphology, crystallographic orientation, and corrosion behavior were studied. The electrokinetic properties (zeta potential) and size distribution statistics in plating bath for the particles were evaluated using dynamic light scattering experiments. The Zn and Zn-MoS 2 deposition process was studied by linear polarization and cyclic voltammetry. Scanning electron microscopy, energy dispersive X-ray analysis, X-ray diffraction analysis, and potentiodynamic polarization measurements were used to characterize the coatings. The addition of MoS 2 to the electrolyte significantly changed the microstructure and crystallographic orientation of the zinc deposits and enhanced the corrosion resistance of the coatings. The morphological and electrochemical properties of the zinc coatings were observed to be significantly affected by the incorporation of MoS 2 particles into the zinc matrix.

“…This conversion coating can be zirconium and/or titanium-based and produces a nanostructured layer on the metal substrate. The advantage of these nanoceramic coatings is being toxic metals and organic compounds free [10,11]. On zinc substrates, the conversion layer produced by nanoceramic coating has no color, unlike the hexavalent chromium one, that confers a range of colors from yellow to black.…”

Corrosion performance of Zr-based coating on substrates obtained by zinc electrodeposition in an alkaline bath is compared to chromate coatings (Cr III and Cr VI). The "nano Zr" is a conversion coating formed by immersion in a hexafluorozirconic acid solution. Since the "nano Zr" coating is transparent, the addiction of a colorant provides color to the surface. In this case, the colorant, when applied after the conversion coating, conferred the yellow color to the surface. The coating produced improves the corrosion protection of the substrate. For this study the samples were analyzed by electrochemical impedance spectroscopy (EIS) and accelerated corrosion test in a humidity chamber. The results showed similar behaviors between the "nano Zr", colorant and the chromate (Cr III) coating. Therefore this kind of conversion coating is a promising substitute for chromate coatings. Keywords: Nano Zr; Immersion process; Electrodeposited zinc; Hexafluorozirconic alkaline solution. COMPORTAMENTO DA CORROSÃO DE UM REVESTIMENTO DE CONVERSÃO À BASE DE ZIRCÔNIO E CORANTES NO AÇO ZINCADO POR ELETRODEPOSIÇÃO ResumoNo presente estudo, avaliou-se o desempenho de revestimentos à base de zircônio e corante sobre substratos de zinco obtidos por eletrodeposição em meio alcalino, em relação aos revestimentos de cromato (CrIII e CrVI). O revestimento "nano Zr" é obtido através da imersão em solução de conversão à base de ácido hexafluorzircônio. Uma vez que o revestimento "nano Zr" é transparente, a adição de um corante proporciona cor à superfície. Neste caso, o corante, quando aplicado depois do revestimento de conversão, confere cor amarela à superfície. O revestimento produzido melhora a proteção contra a corrosão do substrato. Para este estudo ensaios de espectroscopia de impedância eletroquímica (EIS) e testes em câmara úmida foram feitos. Os resultados mostraram comportamentos semelhantes entre o "Zr nano" e corante e o revestimento cromato (CrIII). Por conseguinte, este tipo de revestimento de conversão é um promissor substituto para os revestimentos de cromatização. Palavras-chave: Nano Zr; Processo de imersão; Zinco eletrodepositado; Solução ácida de hexaflúorzircônio.
