Abstract :
This study aims to determine the effect of variations in coating thickness and temperature on low carbon steel test media with themethod paiting on the corrosion rate of a steel material. The method used in this study is the use of variations in the thickness of the paint coating and the immersion temperature. The paint coating uses variations of 1 layer of 75µm thickness, 3 layers of 125µm thickness, and 5 layers of 275µm thickness usingbrand International Paintpaint and temperature variations using temperatures of 80°C, 85°C and 90°C. In this study, seawater was used as an applied problem, which was taken from the Payangan coastal sea of Jember. The test results on the effect ofthickness coating are the greater the value of thethickness coating , the smaller the value of the corrosion rate that occurs. The results of the temperature variation test are that the higher the drying temperature, the higher the quality of the painting results. The test results on the corrosion rate are that the lowest corrosion rate value is found at a temperature variation of 90°C with a thickness of 275µm and the resulting corrosion rate value is 0.006 mm/y, the highest corrosion rate value is located at a temperature of 80°C with athickness of coating 75µm and a corrosion rate value. 0.040 mm/y.
