  Comparative study on structure, corrosion and hardness of Zn–Ni alloy deposition on AISI 347 steel aircraft material

  摘要：

  Zn-Ni alloys were electrodeposited on AISI 347 steel aircraft materials from various electrolytes under direct current (DCD) and pulsed electrodepositing (PED) techniques. The effects of pulse duty cycle on thickness, current efficiency and hardness of electrodeposits were studied. Alloy phases of the Zn-Ni were indexed by X-ray diffraction (XRD) techniques. Microstructural morphology, topography and elemental compositions were characterized using scanning electron microscopy (SEM), atomic force microscopy (AFM) and X-ray fluorescence spectroscopy (XRF). The corrosion resistance properties of electrodeposited Zn-Ni alloy in 3.5% NaCl aqueous solution obtained by DCD and PED were compared using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) technique. Elemental analysis showed that 88% of Zn and 12% of Ni obtained from electrolyte-4 by PED technique at 40% duty cycle for 50 Hz frequencies having better corrosion resistance than that of deposits obtained from other electrolytes.

  The single-phase gamma zinc-nickel alloy (γ-Zn 3 Ni) nanocrystal was deposited on composite graphite electrode at a scan rate of 10,000 mV s -1 . The average particle size obtained was 11.8 ± 3.1 nm. Transmission electron microscopy analysis indicated that codeposition applied potential, i.e., nucleation overpotential, scan rate, and codeposition time were critical on crystal sizing and Ni content

  以10,000 mV s -1 的扫描速率将单相伽马锌镍合金（γ-Zn 3 Ni）纳米晶体沉积在复合石墨电极上。获得的平均粒径为 11.8 ± 3.1 nm。透射电子显微镜分析表明共沉积施加的电位，即成核过电位、扫描速率和共沉积时间对基体中的晶体尺寸和Ni含量至关重要。循环伏安法和 X 射线衍射分析也表明，确实以所使用的扫描速率获得了单相（γ 相）合金。结果还表明，19.0wt%的Ni纳米颗粒均匀地分散在合金涂层的相组成中。

  Ni and Zn are important alloying elements in Mg-based structural materials and hydrogen storage alloys. The isothermal section of the Mg-Ni-Zn system at 400 degrees C was investigated by means of X-ray diffraction (XRD) analysis and electron probe microanalysis (EPMA). The NiZn3 phase was observed to be stable in the as-cast and annealed Ni25Zn75 and Ni23Zn77 alloys. The experimental results confirmed the existence of the ternary tau compound at 400 degrees C. NiZn3, Mg2Zn3, Mg2Ni, MgZn2, MgNi2, and tau show significant homogeneity ranges in the ternary system. The Mg2Zn11 phase is being stabilized in the ternary system at temperatures higher than the melting point of this compound in the Mg-Zn binary system. In the frameworks of the CALPHAD approach, the Ni-Zn system was re-optimized and the thermodynamic description for the Mg-Ni-Zn system was thermodynamically assessed for the first time. The obtained thermodynamic models reasonably reproduce the experimental data on the phase equilibria and thermodynamic properties of the phases. The solidification paths of the representative Mg-Ni-Zn alloys were predicted within the Scheil-Gulliver model using the thermodynamic assessment performed in the present work. The results of the Scheil-Gulliver modeling are in agreement with the EPMA results. (C) 2019 Elsevier B.V. All rights reserved.
