“…Therefore, there are several works concerning the use of alternative, environmentally-friendly electrolytic baths, that can be as efficient as cyanide ions in producing the metallic coatings 4,[6][7][8][9][10] . Among the environmentally friendly electrolytes currently used, citrates, gluconates, sulfamates, tartrates and glycinates are the most studied baths for the electrodeposition of copper alloy coatings 7,[11][12][13] . These compounds are non-toxic complexing agents, easily obtained and degraded 12,14,15 .…”

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 anodic stripping analysis of the deposits was correlated with their morphology, composition and phase structure, both on vitreous carbon and on copper electrodes. The use of tartrate anion as a complexing agent allows deposits to be obtained with a uniform composition and morphology under stirred conditions during the electro deposition process [13]. Corrosion behaviour of zinc plated stainless steel fasteners [14] and zinc plated stainless steel bolts [15] has been investigated.…”

The use of stainless steel 304(SS) tanks to deposit thiourea in industry has been evaluated by studying the corrosion behaviour in 1% thiourea solution, before and after zinc plating. Weight loss method, 1% copper sulphate test, polarization study and AC impedance spectra have been used. The corrosion resistance of SS decreased when zinc was used for electrodeposition. Hence SS vessels electroplated with zinc should not be used to store thiourea solution, in industry.

“…Tin-zinc alloy coatings have good corrosion resistance, frictional properties and ductility, and good solderability. 11,12 In view of their good properties, they proposed as substitutes for other industrial coatings, such as those of cadmium (toxic) and nickel (allergenic). 11,12 Tin-zinc coatings have been used on chassis of electrical and electronic apparatus and on critical automotive parts, such as fuel and brake line components.…”

“…Guaus and Torrent-Burgués investigated tin-zinc alloy electrodeposits obtained from sulphate-gluconate and sulphate-tartrate baths. 11,12 These authors concluded that the zinc content in the alloy increases by using tartrate as complexing agent instead of gluconate. Ashiru and Shirokoff used an alkaline bath (pH 12-13 and temperature of 40-80ºC) and tartrate as complexant to obtain 70/30 to 80/20 tin/zinc alloy compositions.…”

Medidas de transientes de corrente e microscopia eletrônica de varredura foram utilizados para caracterizar o processo de eletrocristalização e morfologia de ligas de estanho-zinco eletrodepositadas sobre Pt, na ausência e na presença de ácido tartárico. O modelo de Scharifker e Hills foi utilizado para analisar os transientes de corrente e revelou que o processo de eletrocristalização da liga SnZn na presença de tartarato, sob as condições estudadas, é governado por nucleação progressiva tridimensional controlada por difusão. Na ausência do complexante, os resultados indicaram que o processo de nucleação varia de instantâneo para progressivo à medida que o potencial de deposição torna-se mais negativo, ou seja, pela incorporação de zinco ao depósito. Os resultados de microscopia mostraram depósitos com duas camadas com morfologias diferentes e que a mesma sofre influência do potencial de deposição Current transients measurements and scanning electron microscopy were used to characterize the electrocrystallization process and morphology of tin-zinc alloys electrodeposited on Pt, in the absence and in the presence of tartaric acid. The model of Scharifker and Hills was used to analyze the current transients and it revealed that Sn-Zn electrocrystallization process in the presence of tartrate, under the studied conditions, is governed by three-dimensional progressive nucleation controlled by diffusion. In the absence of the complexant, the results indicated that nucleation process changes from instantaneous to progressive when the deposition potential becomes more negative, or when the incorporation of zinc occured to the deposit. The microscopic results showed deposits with two layers with different morphologies and is also influenced by deposition potential.
