°C. The oxidizing gas reacts with the iron on the surface, forming a layer of iron oxide (FeO). The deoxidizing gas reduces the FeO back to iron (Fe) at the interface between the Fe and FeO layers. This process is known as the reduction of iron oxide.
The thickness of the FeO layer grows with time, as more Fe is oxidized and more FeO is formed. The rate of growth of the FeO layer depends on the concentration of the oxidizing gas, the temperature, and the rate of diffusion of the oxidizing gas through the FeO layer.
The reduction of FeO back to Fe depends on the concentration of the deoxidizing gas, the temperature, and the rate of diffusion of the deoxidizing gas through the FeO layer. The reduction reaction releases heat, which raises the temperature at the interface between the Fe and FeO layers.
The overall process of oxidation and reduction can lead to the formation of complex oxide layers with different chemical compositions and microstructures. These oxide layers can affect the mechanical, electrical, and corrosion properties of the Fe sheet. Therefore, it is important to control the oxidation and reduction processes in order to optimize the performance of the Fe sheet in various applications.
