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 content of the film. The deposits were found to be globular clusters when high KAg(CN)2 concentrations were used. Finer microstructures and higher Ag contents were observed in deposits produced in electrolytes containing higher KCN concentrations.

Electropolishing of an Fe-Ni-Co Alloy in Acetic Acid-Perchloric Acid Mixture Aksu, Yasemin; ERDOĞAN, METEHAN; Demirci, Gokhan; Karakaya, İshak (2016-06-02) Among Fe-Ni-Co alloys, Kovar (53%Fe-29%Ni-17%Co) designated as ASTM F-15 (1), is a well-known glass-sealing alloy. It is also classified as low–expansion alloy (2). Low expansion is required to avoid internal stresses in applications that involve strong ceramic to metal joining such as in vacuum systems (3-6). Electropolishing is applied to obtain smooth metallic surfaces to gain low outgassing rates from the chamber walls in vacuum applications (7-9). The effects of current density, perchloric acid concent...
Comparison of Structural Properties of Copper Deposits from Sulfate and Pyrophosphate Electrolytes Arslan, Berna; ERDOĞAN, MUSTAFA; İmamoğlu, İpek; Karakaya, İshak (2013-11-01) 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 prop...
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...
A Pulse Voltage Application in Electrochemical Reduction of Solid CaWO4 Powder Goksu, Orhan Gokce; ERDOĞAN, METEHAN; Karakaya, İshak (The Electrochemical Society, 2016-09-01) Scheelite is the most abundant mineral of tungsten, but wolframite is used more than scheelite due to easier dissolution in alkaline solutions used in present processing methods. An alternative method based on electrochemical reduction of CaWO4 by direct current applications in molten salt solutions was recently reported. Pulse voltage and constant voltage reduction mechanisms were compared and an optimization of reduction kinetics was achieved in this study. The results have shown that faster reduction rat...
An Electrochemical Procedure to Form Metal Powders from Recycled Hard Particle Embedded Composite Cutting Tools Altunbasak, Tansu; KUL, MEHMET; Karakaya, İshak (2017-06-01) Used valuable particle embedded composite cutting tools, obtained by powder metallurgy techniques by mixing metallic powders with hard, abrasive particles were electrolyzed for reclamation of metallic powders and valuable particles. The effects of copper ion and sulfuric acid concentrations and pH of the electrolyte, current density and temperature on microstructure of produced copper powders were investigated in detail. Copper powders were characterized by X-Ray diffraction (XRD) and scanning electron micr...
