“…However, in contradiction to the paper by Bouche et al, they noticed a significant decrease in reaction layer thickness for samples at the higher bath temperature of 900°C for long reaction times [67]. Samsu et al reported a progressive increase in ally layer thickness with increasing bath temperature in the range of 700 to 850°C and an increase in dip time at a given bath temperature [73]. The authors mentioned that the metallurgical features of the phases in the steel substrate, like ferrite, pearlite, and austenite, might have affected its growth rate but made no experimental study on this aspect.…”

Among the various surface modification processes, the hot-dip aluminizing process has increasingly evoked considerable attention. This method has proved to be commercially cost-effective and technically better than galvanizing. In contrast to hot-dip aluminized steel components, galvanized components cannot be used in service conditions at elevated temperatures. During the last few years, intensive research by researchers has yielded new insights into metallurgical aspects of aluminized coating in as-dipped and annealed condition. The present review gives a bird’s eye view of the hot-dip aluminizing process, from the early years of its inception to the current research on aspects of the aluminized coating. The progress of research on thermodynamic studies, phase equilibria, phase identification, and their crystallographic features have been traced in this attempt. This review is not restricted to briefing the research performed so far but also points out several issues of discrepancies among the results of the published literature. Special emphasis has been given to the phase development in the coating during annealing and the increasing horizon of application of hot-dip aluminizing to alloy steels in hot stamped conditions. Reference has also been made to state-of-the-art topics embracing the current research on computer simulation software and sophisticated experimental techniques. However, lower surface hardness and economy restrict the wide application of the hot-dipping process.

“…Among all, Ni, P, and Si are found to be affecting the diffusion growth, but no significant changes were found in the corrosion behavior of the coating [6,7]. Other elements such as Sn and Cu that were studied by [8] did not affect the morphology of the galvanized coating. Later, it is found that Mg would enhance the adhesion with the formation of the Fe/Al2Zn3Mg3 phases [9].…”

High corrosion resistance of Zn-Al-Mg (ZAM) alloy is widely used in steel wire rope protection. This alloy, however, due to Mg reactivity, easily induced dross formation containing MgZn2 and Mg2Zn11 which reduced the coating integrity. Thus, in this work, Mg is replaced with various wt.% Sb (ZAS) coated on steel surface will via hot-dip process at the eutectic environment. The thickness of the intermetallic layer and coating thickness were observed using an optical microscope and SEM. It was found that 0.3 wt.% Sb improved the corrosion performance 45.5% (0.00267 mmpy) than ZAM coated steel (0.00490 mmpy) under accelerated corrosive medium of 3.5% NaCl.

“…Peningkatan suhu celupan ini telah meningkatkan nilai mikro kekerasan lapisan antara logam walaupun perubahan itu berlaku pada julat yang kecil. Peningkatan nilai kekerasan secara beransuransur ini disebabkan oleh kewujudan fasa ferit, perlite dan austenit yang lebih banyak semasa proses celupan panas (Frutos et al 2009;Kobayashi & Yakou 2002;Samsu et al 2014). Nilai kekerasan lapisan Al dan subsrat tidak menunjukkan sebarang perubahan yang ketara dengan peningkatan suhu dan tempoh celupan.…”
