| contents | Electrodeposition study of the Cu-Zn-Mo system in citrate/sulfate medium Hugo Sousa Santos Alessandra Alves Correa Murilo Fernando Gromboni Lucia Helena Mascaro Química Cu Zn alloy Mo system composite Alloys and composites that contain molybdenum have been studied due to their excellent properties, such as corrosion resistance and catalytic activity. In this work, the parameters for Cu-Zn-Mo system electrodeposition were studied, such as deposition potentials and concentration of electroactive species. The deposition potentials were examined using cyclic voltammetry and anodic linear stripping voltammetry (ALSV), the deposit morphology was evaluated using scanning electron microscopy (SEM) and crystallographic characterization was carried out for X-ray diffraction (XRD). The voltammetry studies indicated co-deposition of the metals in potentials more negative than -1.2 V, and a potential deposition at -1.5 V was chosen. The coatings presented morphology compact with small agglomerated particles with cauliflower structures, and the content of molybdenum, copper, and zinc ranged from 5 to 8%, 30 to 40% and 20 to 28%, respectively. 2019 artículo científico 0100-4670 https://www.redalyc.org/articulo.oa?id=42961598006 https://www.redalyc.org/journal/429/42961598006/ https://www.redalyc.org/journal/429/42961598006/html/ https://www.redalyc.org/journal/429/42961598006/42961598006.epub https://www.redalyc.org/journal/429/42961598006/movil https://doi.org/10.26850/1678-4618eqj.v44.1SI.2019.p26-35 en http://www.redalyc.org/revista.oa?id=429 Eclética Química application/pdf Universidade Estadual Paulista Júlio de Mesquita Filho Eclética Química (Brasil) Num.5 Vol.44 |
