“…That is consisting of copper and tin metals. The variations of tin composition significantly affect and improve the alloy characteristics and mechanical properties [1], such as ductility, solderability [2], low surface tension [3] and increasing of Sn content provides a higher corrosion resistance. The electroplated Cu-Sn alloys are used for decorative finishing of various metallic articles [4], industrially for metal coatings and microelectronic applications [5,6].…”

“…The tartrate ion is an organic additive in the electrodeposition process of different metals and alloys, as have been reported in the literature 17,18 . Sodium tartrate was used as an additive for the electrodeposition of Cu-Sn alloys from an acid bath, producing levelled coatings 19,20 . The tartrate ion is known as a complexing agent for Cu (II) and Sn (II) ions.…”

This work proposes the production of Cu-Sn alloy coatings with anticorrosive properties, using an environmentally non-aggressive bath. The coatings were electrodeposited on carbon steel substrate AISI 1020 using an electrolyte containing CuCl 2 and SnCl 2 , and sodium tartrate as the complexant agent. The produced coatings were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), inductively coupled plasma optical emission spectrometry (ICPOES) and electrochemical impedance spectroscopy (EIS). The film showing the highest corrosion resistance was obtained using j = 100 Am -2 . This coating was composed by 95.18 % m/m Cu and 4.83 % m/m Sn, and presented a uniform surface, without defects and small grain sizes. These characteristics probably contributed to the formation of Cu-Sn protective film onto steel substrate from a tartrate bath.

“…The cyanide baths are used frequently in commercial electrodeposition of Cu-Sn alloys and give high-quality deposits, but they cause environmental problems related to the use and disposal of cyanide. [4,[17][18][19] Citrate, thiocyanate, tartrate, and pyrophosphate baths are used for Cu-Sn electroplating, but these electrolytes have several drawbacks and safe alternatives have been sought. [4,15,20] Nevertheless, tripolyphosphate (TPP) electrolytes that have already been employed for electroplating of high-quality bronze coatings are suitable for Cu-Sn powder electrodeposition.…”

“…The leading selection of TPP as complexing agent is a result of its nontoxic nature, low cost, and ability to compose stable soluble complexes with copper and tin ions. [4,21] Carlos et al [17] have investigated the effects of tartrate addition on chemical stability of an acidic Cu-Sn bath. They found that the deposition efficiency was changed with the presence of tartrate as an additive in Cu-Sn baths.…”

In this article, the electrodeposition process of Cu-Sn alloy powders from tripolyphosphate (TPP)-based electrolytes was investigated as a function of deposition parameters. The effects of deposition parameters such as current density, electrolyte composition (Cu/Sn mole ratio), mechanical stirring speed, and temperature on the Cu content of alloy powder and cathodic current efficiency were evaluated using the response surface methodology (RSM). The empirical models developed in terms of deposition parameters were found to be statistically adequate to describe the process responses. The study revealed that as far as the copper content was concerned in the alloyed powders, all parameters selected had positive correlations. However, a high stirring speed and low current density led to a greater current efficiency. The morphology and chemical composition of the electrodeposited Cu-Sn alloy powders were investigated using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and inductively coupled plasma (ICP) analysis. An SEM analysis showed that the powder morphology was affected considerably by the cathodic current density and stirring speed.
