국문 초록

This study investigates the corrosion behavior and the formation of corrosion products in carbon steel exposed to atmospheric conditions at temperatures of 600-800°C for 50-200 hours. The experimental results revealed that at 600°C, corrosion products gradually formed over time, and the corrosion rate exhibited a parabolic behavior. In contrast, at 700°C and 800°C, the corrosion rate continued to increase over time, showing a linear behavior. Even after the formation of corrosion products on the surface, the corrosion rate consistently increased. Cu coated specimens exhibited lower corrosion rates compared to un-coated specimens, highlighting the significant role of the coating layer in improving corrosion resistance. Additionally, the corrosion rate increased with temperature, which can be attributed to the enhanced chemical reaction rate at higher temperatures, indicating that corrosion reactions occur more rapidly at elevated temperatures.
