“…Interestingly, a similar phase transformation occurred in wire-arcsprayed Zn-15Al alloy coatings produced from pre-alloyed wires, which were subjected to a temperature of 500 • C [19]. The results obtained from the EDS analysis were also consistent with previous reports in the literature [29,30]. The SEM images taken at ×2500 revealed the microstructural arrangement of these phases where, in a lighter matrix of the η phase, the peanut-shaped lamellar structure of the eutectoid (α + η) phase was present, as well as the coarse lamellar structure of the eutectic (β + η) surrounding it.…”

This paper examines the impact of fire on the microstructural, mechanical, and corrosion behavior of wire-arc-sprayed zinc, aluminum, and Zn-Al pseudo-alloy coatings. Steel plates coated with these materials were subjected to temperatures in increments of 100 °C, starting from 300 °C and progressing until failure. Microstructural characterization, microhardness, abrasion resistance, and electrochemical impedance studies were performed on the post-fire coatings. The findings from this study show that heat had a positive impact on the performance of zinc and Zn-Al pseudo-alloy coatings when they were exposed to temperatures of up to 400 °C, while aluminum coatings maintain their performance up to 600 °C. However, above these temperatures, the effectiveness of coatings was observed to decline, due to increased high-temperature oxidation, and porosity, in addition to decreased microhardness, abrasion resistance, and corrosion protection performance. Based on the findings from this study, appropriately sealed thermal-spray-coated steel components can be reused after exposure to fire up to a specific temperature depending on the coating material.

“…The impact fracture surface of the as-cast alloy was quite rough and exhibited brittle fracture characteristics with cleavage crack on the margin of the plane of brittle fracture, as seen in Figure 5(a). Zn-Al based alloys especially in the as-cast state exhibit brittle fracture characteristics due to the residual stresses and dimensional instability caused by the nonequilibrium cooling rates of the alloying elements (Turhal and Savaşkan, 2003;Hasan et al, 2020). Dimensional instabilities and residual stresses, which cause brittle fractures in the structure could be considerably eliminated by prolonged aging after solution treatment (Chen et al, 2008;Zhang et al, 2020;Meng et al, 2021).…”

“…The effect of Al content on the microstructure and properties of Zn-Al solder alloys has been investigated by previous researchers, but most of the related studies have focused on Zn-Al alloys in the drawn-state [18][19][20][21][22][23]. However, in the actual production process, we found that even though the Zn-Al solder has good plasticity, if it is not annealed from the treatment the solder is easy to fracture after multiple drawings, which obviously greatly extends the production cycle of the solder products.…”

Zn-Al alloy with the addition of Al (5–25 wt.%) was fabricated into as–cast and rod–shaped alloys. SEM/EDS and XRD technology were used to examine the impacts of the Al–element content on the alloys’ microstructure, mechanical characteristics, electrical conductivity, wetting ability, and corrosion resistance. The findings demonstrate how the Zn-Al alloy’s microstructure is dramatically altered by the different additions of the Al content. When the Al content reaches 15 wt.%, the eutectoid structures of the as–cast Zn-Al alloy are the finest, and the microhardness and tensile strength of the extruded–state alloy reach their maximum and exhibit the best corrosion resistance. The spreading area of the Zn-15Al solder alloy achieves its maximum on the 6061 Al plate, while it reaches its minimum on the T2 Cu plate. Furthermore, the electrical resistivity of the Zn-Al alloy continuously decreases as the Al content increases.
