Aluminum is quite often plated to combine the advantages of the light metal with modified surface properties. In this study, copper strike electrodeposits obtained from cyanide and pyrophosphate strike baths were compared in terms of microstructure, and copper pyrophosphate strike was found to yield smoother deposits. Furthermore, about 50 µm thick copper depositions on the strike plated aluminum surface, were prepared from acid copper sulfate and copper pyrophosphate electrolytes to compare structural properties of the deposits. Comparison and characterization of copper electrodeposits from copper sulfate and pyrophosphate electrolytes were performed by potentiometry, SEM, roughness, and XRD analyses. Smoother and finer grained copper deposits were obtained from pyrophosphate electrolyte especially at low current densities.

Formation and Characterization of Sub-Micron Inert Particle Embedded Nickel Composite Coatings Yılmaz Tüzün, Özgül; Karakaya, İshak (2017-06-01) Composite coatings have a wide range of application areas requiring improved mechanical and tribological properties. Due to its enhanced properties, Ni-Al2O3 electro-co-deposition rather than pure Ni electrodeposition was investigated. A typical sulfamate bath was used to evaluate the effects of current density on hardness and the amount of deposited Al2O3. It was found that increase in current density increases the hardness and deposited wt.% Al2O3 particles within the parameter ranges covered in this stud...
The Role of Electrolyte Composition on Codeposited Ag and Cu ulu, fulya; Demici, Gokhan; ERDOĞAN, METEHAN; Karakaya, İshak (The Electrochemical Society, 2016-09-01) The eutectic Ag-Cu composition is a common brazing alloy. A complex ion bath containing KAg(CN)2, CuCN, KCN and K4P2O7 was used to codeposit Ag and Cu. The effects of KAg(CN)2, KCN and K4P2O7 concentrations on the composition and morphology of electrodeposited Ag-Cu films was investigated in this study. A constant CuCN concentration of 0.1 M was used. The increase in KCN and KAg(CN)2 concentrations caused major increases in Ag contents, but increase in K4P2O7 concentration caused a minor decrease in Ag cont...
Nickel and Gold Coatings of Germanium and Kovar Substrates Cetin, Yasin; ERDOĞAN, METEHAN; Demirci, Gokhan; Karakaya, İshak (2016-06-02) The integration of germanium to other materials such as Kovar® (registered trademark of Carpenter Technology Corporation), an Fe-Ni-Co alloy, by soldering requires a surface preparation due to poor wetting characteristics of germanium. Coating (metallization) by successive electroplating of 3 mm wide nickel and gold frames well adhered to the outer edge of a circular germanium window and kovar body was applied to attain successful joining of germanium to kovar. Surface cleaning of parts to be joined or plat...
Electrochemical Formation of Brazing Alloys on Metal Substrates Ulu, F.; Karakaya, İshak; Demirci, G.; ERDOĞAN, MUSTAFA (2013-11-01) CusilTM is a eutectic brazing alloy of 72% silver, 28% copper composition; used to join different materials. The large difference between the standard reduction potentials of silver (0.799V) and copper (0.337V) makes their electrochemical codeposition difficult. A complex ion bath containing KAg(CN)2, CuCN and KCN was used to bring the reduction potentials closer together. The effect of electrolyte concentration on composition and microstructure of electrodeposited Ag-Cu films was investigated at 25oC. A cu...
Investigation of Au-Ag-Cu Alloy Electrodeposition to Electromechanical Systems Cagan, Berkay; ERDOĞAN, METEHAN; Karakaya, İshak; Yilmaz, Cemil; Yurdakul, Burak (2020-04-01) © 2020 ECS - The Electrochemical Society.Electromechanical systems, which provide electrical power and data connection between moving terminals require high conduction and erosion resistant surfaces. Transfers of electrical power and data are accomplished by the contact of drum and brush wires. The simultaneous electrochemical deposition of desired Au-Ag-Cu alloy compositions, which can be used to coat the brush wires, was investigated in this study. In the scope of the study, the static potential and cycli...
