“…Thus, galvanic cells of Sb 3 Zn 4 /Zn will be formed. An adherent coating is deposited with the addition of Sb through barrier and galvanic protection (Peng et al, 2020). Third, an appropriate temperature and time for hot-dip galvanizing is another key factor to optimize or regulate the as-prepared galvanizing coating to improve the hot-dip galvanizing process (Fasoyinu and Weinberg, 1990;Asgari et al, 2007;Culcasi et al, 2009).…”

“…With the addition of zinc, a modification of the solubility of gallium is induced as a single phase. There seems to be better metallurgical homogeneity due to zinc resulting in higher efficiencies [28,29]. Muazu Abubakar et al [30] have found that the highest anode efficiency of Al-Zn-Mg Alloy for sacrificial anodes is 89% by the formation of a Zn intermediate alloy.…”

In this manuscript, the influence of gallium content additions of Al-Zn-In-Mg alloy was investigated through electrochemical techniques and microstructure observation in 3.5 wt% NaCl solution. The results indicated that Al-Zn-In-Mg-0.03Ga alloy has the best discharge performance among all alloys. We propose that this is due to the fact that gallium addition to the Al-4Zn-In-Mg alloy improves the discharge activity of the alloy as well as elevating its anodic efficiency. In particular, the effect of gallium addition to improve discharge activity tends to be a parabolic curve, in which there is an increase when the gallium is first added that rises to the maximum anode current efficiency of about 98.25% whenever gallium content is 0.03 wt%.

“…Solidification structure of alloy is the most significant for the performance and the surface appearance of the final products. A large number of scientific literature focused on the effect of alloying elements (Mg, Ti, Zr, Sb, Re, etc) on the microstructure and corrosion resistance of zinc-based coating [13][14][15][16][17][18][19]. It is believed that the corrosion and mechanical properties was strongly affected by the microstructure of zinc alloy coatings.…”

In this article, the effects of Ti and Zr elements addition on the microstructure and corrosion resistance of Zn-2.5Al-2Mg alloy were studied. The microstructure, micro hardness, corrosion resistance of Zn-2.5Al-2Mg alloy were investigated by x-ray diffraction (XRD), Scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS), Rockwell hardness tester and Electrochemical workstation, respectively. The result shows that the solidified structure of Zn-2.5Al-2Mg alloys was refined by Al 3 Ti, Al 3 Zr and Al 3 (Ti, Zr) which act as a heterogeneous nucleation site. Moreover, the Rockwell hardness of Zn-2.5Al-2Mg alloys with the addition of Zr was significantly increased. The hardness of this alloy with the same amount of Zr and Ti addition is lower than that of the alloy with Zr addition alone, but obviously higher than that of the alloy with Ti alone. The corrosion resistance of the Zn-2.5Al-2Mg alloys with the same amount of Zr and Ti addition was improved significantly.
