The influence of SiC and Al2O3 micrometric particles on the electrodeposition of ZnNi films and the obtainment of ZnNi–SiC and ZnNi–Al2O3 electrocomposite coatings from slightly acidic solutions

Zn–Ni–Al2O3 nano-composite coatings prepared by sol-enhanced electroplating

“…However, SiC reduced crystallite size of the Zn-Ni alloy. Tulio et al [8] investigated the influence of micro SiC and Al 2 O 3 particles on the Zn-Ni properties from a slightly acidic solution. It was evident from their study that SiC decreased the Ni/Zn ratio in the coatings while Al 2 O 3 particles did not affect the Ni content in the coating.…”

Effects of SiC and Al2O3 particles on the electrodeposition of Zn, Co and ZnCo. I. Electrodeposition in the absence of SiC and Al2O3

“…ZnCo electrodeposition is known to be anomalous, in that the less noble element, Zn, is deposited in preference to the nobler one, Co. Several hypotheses have been proposed to account for anomalous electrodeposition [34][35][36][37][38][39][40][41][42][43][44]. In some cases, suspended ceramic particles are known to interfere with anomalous electrodeposition [5,45,46].…”

Influence of Organic Additives and of Stabilized Polymeric Micelles on the Metalographic Structure of Nanocomposite Zn and Zn-Co Coatings

“…However, the protective characteristics of the galvanic alloys often need additional improvement, especially in more aggressive media. A possible way to extend the service life of the zinc is obtaining composite coatings by using different inorganic (oxides, ceramics, carbides, such as ZrO 2 , TiO 2 , SiO 2 , Fe 2 O 3 , SiC etc) [10][11][12][13][14] or polymeric micro-(nano)particles, which generally also exhibit high corrosion resistance [15][16][17][18][19]. One serious problem could be the possible agglomeration of the particles in the electrolyte, and their sedimentation on the bottom.…”
