“…Based on the results above, the surface of the coating mainly consists of Fe-Al compounds FeAl. It is indicated that with the increase of temperature, the FeAl were formed by Fe-Al alloying reaction, at the same time the relative position of Fe-Al compounds were moved upward to the surface because of the penetration of liquid zinc with high-density downward into the substrate, and this is consistent with the phenomenon reported in the study by Zhao et al 37) At the same time, for GI coating, the element distributions still keep homogeneous like at lower temperatures. The results above reveal that unlike the result at 450 and 600°C, the interdiffusion reaction between coating and substrate of Zn-Al-Mg trends to be higher than GI coating at 700°C.…”

“…Some previous researches show that the existence of Al suppresses Fe-Zn alloying reactions by forming a Fe-Al intermetallic layer to obstruct the interdiffusion between Fe and Zn. 37,38) In this study, the Fe-Al inhibition layer could be observed at 450°C, so the key theories related to this behavior can be explained and summarized as follows: Zn-Al-Mg is an Al-enriched coating layer rather than GI coating, when two type coatings are heated above the melting temperature, the coating and substrate atoms trend to interdiffuse at the interface. In Alenriched Zn-Al-Mg coating, the Fe-Al intermetallic layer formed firstly at the coating/substrate interface, so that the process of Fe-Zn alloying reaction is retarded and the formation of solid Fe-Zn phases are suppressed.…”

“…Furthermore, regarding the alloy composition of the coating, a method was proposed to adjust the Al content in the Zn-xAl-1.8Mg coating to increase the thickness of the Fe-Al inhibition layer, thereby retarding the interdiffusion of Fe and Zn, aiming to improve this key issue for an industrial application. However, research revealed that with an increasing heating temperature and prolonged heating time, the Fe-Al intermetallic compound layer may gradually break down, leading to the penetration of liquid Zn into the steel substrate, resulting in the occurrence of LME phenomenon [35]. In addition, it was found that the uniform α-Fe(Zn, Al) layer formed during the high-temperature tensile process of Zn-Al-Mg coated plates can prevent the direct contact of the liquid metal with the steel substrate, thereby completely suppressing LME at high temperatures [20].…”

“…Abdulaziz et al [15] study found that hot dip galvanized Zn-Al coatings on the surface of steel rebars have better corrosion resistance than pure zinc coating. Zhao et al [16] reported the liquid metal embrittlement susceptibility of Zn-Al-Mg/Sn. They found that the addition of the Sn element in the alloy coating improves the stability of the inhibition layer, and the coating had better crack propagation resistance than that without the Sn element.…”
