“…The weight gain of coated sample is about 1 mg/cm2 compared to about 4 mg/cm2 for blank sample in TGA curve. This indicates that the ceramic coating is preventing oxidation of steel surface at high temperature of 500 ⸰ C (Boissonnet et al, 2023). On the basis of obtained data, it can be concluded that the ceramic coating improves the corrosion r resistant of mild steel sample.…”

In high temperature environments where oxidation occurs which effects the metal in multiple ways. High temperature corrosion is typically seen in ductile steel. This can cause abrupt failure and reduce a metal's mechanical properties. A variety of ceramic coatings are available that can be applied to enhance functionality and prevent corrosion, particularly at high temperatures. The majority of ceramic coatings are typically electrically nonconducting, making them excellent insulators. It also has a high melting temperature of up to 4000⸰F and remarkable abrasion resistance. Due to these characteristics, they offer exceptional corrosion resistance and strong abrasion resistance in high temperature conditions. In this research, the team synthesize ceramic coating which may provide exceptional abrasion resistant as well high temperature oxidation resistance. Before selecting the ingredients, it needs to be examined the compatibility between mild steel (sample) and constituents of ceramic coating, majorly the thermal expansion characteristics. It must be identical otherwise fractures can be produced on the coated surface of a metal. Samples were made as per demand, following collecting a sample and cleaned accurately to attach the coating appropriately. After application of coating on sample it should place in furnace which promote diffusion on a metal surface and construct protective barrier. Further, dipping the sample in 3.5% NaCl solution for 21 days and execute the OCP and EIS test of naked sample and coated sample correspondingly for 5 days. Potentiostat provides several graphs viz OCP, Bode plot, Nyquist impedance plot and Tafel Extrapolation. High temperature oxidation resistance of the ceramic covering was investigated using TGA analysis. The weight gain of coated sample is roughly 1mg/cm2 compared to about 4 mg/cm2 for plain sample in TGA curve. This illustrates that the ceramic coating is averting oxidation of steel surface at high temperature of 500ºC.

“…This is obvious since the enamel coatings are already oxide-based glasses, and they would not be seriously affected by oxidation until softening at service temperatures. The enamels’ oxidation resistance in Ar/water vapour at 650°C was studied with promising results [59]; however, the further investigations with longer-time exposure considering possible enamel's hydrolysis issues, as conducted in the present work, should be required.…”

Vitreous ceramic-like enamel coatings can be applied onto low-alloy and carbon steel components of various configurations, including tubulars, by different cost-effective technological methods achieving thicknesses up to 300 µm. Corrosion resistance of the enamel coatings in acidic environments, boiling brines and high temperaturehigh pressure (HT-HP) steam with a presence of CO 2 -H 2 S containing gases simulating some processes in refinery, oil & gas and geothermal production was tested and evaluated. Specifically, the testing in simulating HT-HP downhole production conditions was conducted for the enamel coatings for the first time. Microstructural examination and analysis of the obtained enamel glassy coatings revealed their insignificant compositional and structural degradation. A high level of steel protection by enamelling in considered environments demonstrated these coatings' potential for different corrosion-related industrial processes.
