Abstract

Corrosion problems often occur in petroleum industry surface facilities caused by materials made of steel metal. The steel material is susceptible to corrosion because it interacts directly with the surrounding environment. One of the things that affects the rate of corrosion is temperature. To slow the rate of corrosion growth, use the latest way, namely by coating steel metal with GO coating. In this study, the basic ingredient of GO was from carbon battery waste synthesized using the LPE (Liquid Phase Exfoliation) method. Synthesized GO already has function group properties according to GO characteristics. The application of GO coating to steel samples has been studied based on the effect of temperature and thickness of GO coating. It is found that the lowest temperature of 35 °C has the smallest corrosion rate. The temperature increase of 40°C the rate of corrosion increased by 75% from the initial temperature, but GO coating managed to withstand the percentage of corrosion rate when the temperature was raised to 45 °C with a percentage of 44%. Based on variations in the thickness of GO coating obtained the result that the thickness of the thickest layer is 1.67 mm has the smallest corrosion rate value between the thickness of the coating layer 0.47 mm, 1.10 mm, and 1.31 mm. The most efficient insulation efficiency is obtained at the thickest GO coating thickness of 1.67 mm.
