“…Cyanide-based solutions-which are not desirable due to environmental issues-were used as deposition electrolyte for Zn-Cu coatings in industry [25,26]. To solve these issues, environmentally-friendly and cyanide-free media including non-aqueous (ionic liquids [27] and deep eutectic solvents [28]) and aqueous media (gluconate [29], EDTA [30,31], mannitol [32], tartrate [33], ammonia [34], and pyrophosphate-based complex solutions [35,36]) have been used for Zn-Cu deposition. Specifically, pyrophosphate deposition bath is an environmentally friendly electrolyte [37], and metals/alloys obtained in this electrolyte do not produce their oxide/hydroxide forms [38][39][40][41].…”

Zn-Cu alloy was deposited onto AZ63 substrate, and the corrosion behaviour of resulting modified electrodes was investigated in 3 wt % NaCl solution in comparison with uncoated AZ63. Electrochemical, structural, and morphological study of the coating is presented. SEM images reveal that the surface morphology of the films is uniformly small spherical grain distributions. The XRD patterns illustrate polycrystalline structure and the formation of peaks corresponding to hexagonal close-packed ε-phase of Zn-Cu with various crystallographic orientations. Cyclic voltammetry was used to determine the potential ranges where the various redox processes occur. Linear sweep voltammetry results illustrate that longer exposure of uncoated AZ63 in NaCl solution produces a greater corrosion potential shift because of the formation of an oxide layer that did not prevent the progression of corrosion attack. The corrosion resistivity of Zn-Cu coated AZ63 is approximately two orders of magnitude greater than that of uncoated AZ63.

“…A microestrutura do Zamac injetado sob pressão apresenta grãos mais refinados e melhor distribuídos em comparação com o Zamac fundido por gravidade. Isso mostra que o processo de produção tem influência na microestrutura do produto final [5,9]. As análises das microestruturas mostram de que quanto maior for a temperatura de fundição, mais tempo o Zamac vai demorar para se solidificar sem nenhuma ação externa, trazendo como consequência um maior tamanho de grão da peça solidificada.…”

No entanto, os processos de sua obtenção, por injeção sob pressão e injeção centrífuga, geram porosidade e, consequentemente, aumento de sucata. Por outro lado, estudos mostraram que fusão por gravidade não apresenta tais problemas. Nesse sentido, o objetivo deste artigo foi tratar termicamente peças de Zamac injetadas sob pressão, com a finalidade de obter comportamento semelhante às peças fundidas por gravidade. Para tanto, peças injetadas sob pressão foram tratadas termicamente, abaixo da temperatura de fusão. A caracterização morfológica dessas amostras foi obtida por MEV. Observou-se que o tratamento térmico acima da temperatura eutetoide apresentou melhor resultado com respeito à porosidade observada.

“…As summarized in Table 1 , there is no Zn-Sn alloy or compound but only Cu-Sn and/or Cu-Zn compounds. In room temperature electrodeposited Cu-Zn samples, phases ranging from the entire spread of the binary phase diagram, including β-CuZn, γ-Cu 5 Zn 8 and ε-CuZn 5 , have been observed 35 36 37 . Among them, Cu 5 Zn 8 is a stable room temperature phase 38 .…”

We report the synthesis and characterization of Cu2ZnSnS4 (CZTS) with controlled phase purity. The precursor was first prepared using sequential electrodeposition of Cu, Zn, and Sn in different orders. The Cu/(Sn+Zn) ratio in each stacking order was also varied. The precursor was subjected to annealing at 200°C and sulfurization at 500°C in a 5%-H2S/Ar atmosphere for the formation of CZTS. The phase evolutions during the electrodeposition and annealing stages, and the final phase formation at the sulfurization stage were examined using both x-ray diffractometry and Raman spectroscopy, both of which are shown to be complimentary tools for phase identification. Detailed growth path is therefore reported. We also demonstrate by controlling the stacking order and the Cu/(Sn+Zn) ratio, CZTS with a phase purity as high as 93% is obtained.
