Temperature-Dependence of Deposition Rate and Current Efficiency in Platinum Electrodeposition at a Fixed Average Current Density
We have investigated the formation of a platinum thin film from a simple solution of dihydrogen hexachloroplatinate in a low temperature range of 283 to 295 K by a pulse current technique. Despite the low temperature, the platinum thin film observed with a confocal laser scanning microscope does not comprise particle aggregates but dense layer with a small surface roughness that tends to satura...
متن کاملCathodic Electrodeposition and Characterization of YAG Nanostructure: Effect Current Density on the Morphology
Abstract YAG (Yttrium Aluminum Garnet) was successfully prepared through cathodic electrodeposition process using applying different current densities to the mixture of YCl3 and AlCl3 dissolved in water/ethanol 1:1 solution. Hydroxide precursors were cathodically grown on the cathode surface (at different current densities) and then the obtained hydroxide powder was heat-treated at 1100 °...
متن کاملEFFECT OF SUBSTRATE TEXTURE AND DEPOSITION CURRENT DENSITY ON PROPERTIES OF NiNANOCRYSTALLINE ELECTRODEPOSITS
Abstract: Nickel was electrodeposited onto copper substrates with high {111} and {400} peak intensities. The grain size of coatings deposited onto the copper substrate with a higher {111} peak intensity was finer. Spheroidized pyramid morphology was obtained at low current densities on both copper substrates. By increasing the deposition current density, grain size of the coating was increased ...
متن کاملEffect of Current Density, Temperature, and Contact Paste on Flash Sintered 8YSZ
Flash sintering has been investigated as a modern sintering method through examining the effect of processing parameters such as current density, temperature, and contact paste on the flash sintered 8YSZ characteristic. 95% of theoretical density was achieved at 800°С in 30sec with a field intensity of 100V.cm-1 and a current density of 160mA.mm-2. Such relative density in conventional sinterin...
متن کاملZinc-Nickel Binary Alloys Electrodeposition of Steel Using Pulse Current
Zinc-Nickel electrodeposits have been widely adopted for surface treatment of automobile steel sheet for high corrosion resistance. In this work the effect of pulse parameters on the Zn-Ni alloy electrodeposits was investigated. The hardness, thickness, corrosion resistance and composition of deposits thus produced were investigated. The surface topography of the deposits was also observed in S...
