Electrodeposition of Nanostructured Magnesium Coatings
In this work, we report on the electroplating of ultrafine and uniform magnesium (Mg) films on copper (Cu) and carbon nanotube (CNT) paper substrates. By controlling the process parameters and utilizing the pulsed deposition method, the average grain size of Mg was reduced to nanodimensions. Surface pretreatment of the substrates by depositing a seed layer was found to be an efficient strategy ...
متن کاملOxidation Behaviour of Ni-Cr-Y2O3 Composite Coatings Synthesised by Sol Enhanced Pulse Electroplating
The objective of this study was to improve the oxidation resistance of electroplated Ni-Cr coatings by introducing a fine dispersion of yttria (Y2O3) nanoparticles to the coatings. A technique was developed to produce Y2O3 nanoparticles nm in size. Electroplating conditions were also investigated and it was found that pulse plating could produce high quality coatings without cracking. The Y2O3 ...
متن کاملInfluences of Bath Stirring Rate on Synetics of Nano Composite Ni-SiC-Gr Coatings on St37 via Electrodeposition Process
In this study, electrochemical deposition of Ni-SiC-Gr nano composites was studied. The Watts bath was used for electrodeposition. The SiC and graphite powders were suspended in the electrolyte and stirred. The effects of changes in bath stirring rate on the composite coating were investigated. The X-Ray diffraction (XRD), scanning electron microscopy (SEM) and field emission scanning electron ...
متن کاملELECTRODEPOSITION AND CHARACTERIZATION OF Ni - Co - P - BN DISPERSION COATINGS
Functional plating such as alloys or dispersion coatings have been widely used in metal finishing industry. In general, dispersion coatings are deposited from plating baths containing suspended particles such as metal oxides, carbides, metals or organic materials,(l-3) Codeposited particles in the dispersion coatings have the remarkable influence on the properties of the deposits depending on t...
متن کاملPulse Reverse Electrodeposition of Spherical Ni-MWCNT Composite Skein
Watt’s bath and pulse reverse (PR) electrodeposition is used to produce spherical nickelmultiwall carbon nanotubes (Ni-MWCNT) of 2.00, 0.93, 1.63 and 6.71 μm diameter and a variety ofsize distributions. For 60 cycles, an absolute electrodeposition current of 18 A/dm2 is applied atcurrent ratios of ii = idissolution/ideposition = 0, 0.077, 0.200 and 0.368. A simple exponential equation isfitted ...
