Oxidation Resistance And Corrosion High Temperature Of Fecraitiy-mosi2 Layers
Oxidation Resistance and High Temperature Corrosion in Fecral-MoSi2 Layers: A Comprehensive Study
Introduction
The development of advanced materials with improved oxidation resistance and high temperature corrosion properties is crucial for various industrial applications, particularly in sectors that face extreme conditions. In this study, we focus on the low carbon steel coating and its characteristics, with a specific emphasis on the oxidation resistance and high temperature corrosion properties of fecral-MoSi2 layers. The coating process is carried out using two different methods: the fire spray technique and the spark plasma sintering (SPS) technique. Our objective is to determine the optimal coating method and understand the effect of variations in the concentration of MoSi2 on the performance of the layers.
Materials and Methods
The substrate used in this study is stainless steel ST41 (low carbon steel) with a thickness of 3.0 mm and an area of 1.0 x 1.0 cm². The substrate is first ultrasonically cleaned using methanol and then cleaned with sand before the coating process. The coating is carried out using the fire spray technique with variations in the concentration of MoSi2 in the fecral composition, namely x MoSi2, with x = 10, 20, and 30 in the percentage of weight (% WT) sprayed on the ST41 steel substrate.
Results and Discussion
The results of X-ray diffraction (XRD) show that the composition of the coating layers consists of the phase of Fe2O3, Fe3O4, Al2FeO4, SiO2, and Al2O3. After testing oxidation at high temperatures, it is found that low carbon steel produces a thick layer of Fe-oxide and there are cracks on the surface of low carbon steel. However, low carbon steel that has been coated with fecral-MoSi2 produces a layer of Fe2O3 which effectively increases resistance to oxidation at high temperatures.
The results of the SPS technique show that the fecral-MoSi2 layer prepared in low carbon steel exhibits improved resistance to oxidation and corrosion. The solid coating layer consists of phases (Fe, Cr) and MoSi2 after high temperature oxidation testing. The formation of a thin protective layer of Al2O3 is also observed, while oxide compounds such as (Cr, Fe)2O3, Al2O3, and Fe3O4 are formed after high temperature corrosion testing.
Conclusion
The effect of variations in the concentration of MoSi2 and the coating method used will determine the performance of layers in dealing with extreme conditions. By understanding the behavior of this material, we can develop materials that are more durable and efficient in industrial applications, especially in sectors that face high temperatures and corrosion. The right coating not only increases the life of the material, but also reduces the cost of maintenance and replacement of components. Therefore, further research on the optimization of composition and coating methods is needed to face future challenges in material technology.
