Abstract

Corrosion is an electrochemical reaction process between metals and the environment that produces ions that can degrade the quality of metals. Analysis of corrosion in moderate carbon in the environment of water, air, and sodium chloride is: to find out the effect of water (H2 O), air (O2), and sodium colicide (NaCl) on the rate of corrosion in medium carbon steel and to know the type of corrosion and microstructure of the material.In this study, before corrosion carbon steel specimens were being conducted cyclic tests. Corrosion processes include immersion (soaked in a Solution of NaCl) and without immersion (left in free air). The implementation of the clubing for 8 x 24 hours (192 hours). Then the specimen is weighed using digital scales to determine the rate of corrosion where the corrosion material is cleaned first before the initial and final weighing, and then tested cyclically and look at the microstructure.The results of research that has been done obtained that the corrosion rate of carbon steel samples is moderate at a mass of NaCl 50 gr, 70 gr and 90 grams which is 0.3612 mm / y, 0.543 mm / y and 1.028 mm / y as for. The magnitude of corrosion rate in NaCl mass of 90 gr in the 50 gr and 70 gr is caused by several factors, namely air temperature, humidity, and greater NaCl mass. Corrosion formed in a sample of medium carbon steel is corrosion of strained cracks and corrosion of wells. And obtained the main constituent elements of the plate are iron (Fe) and carbon (C).
