PERBANDINGAN KOROSI BAJA KARBON RENDAH PADA AQUADES DAN AIR TERCEMAR SAMPAH SERTA PENGARUH PROTEKSI KATODIK ANODA TUMBAL PADA KEADAAN YANG SEBENARNYA

- In the world of industrial corrosion is one of the factors in the cause of the failure. His presence makes all objects interact suffered a loss or failure of either objects of metal and non metal. So that this problem does not continue the need for a method to prevent and overcome so that doesn't happen again corrosion. One of the large number of methods to cope with the onset of corrosion that is controlling the corrosion potential of metals change way or corrosive media. The purpose of this research was to understand and analyse the comparison of low-carbon steel corrosion in polluted water and rubbish aquades as well as the influence of cathodic protection anodes tumbal on the State of the actual. Of the research obtained the longer soaking low carbon steel corrosion rate then declined resulting metals increasingly passive. This is the case in low-carbon steel without protection or with the protection. The results of the rate of corrosion of low carbon steel without protection on polluted water waste at the time of soaking 336 hours i.e. 20.5836 mpy and 504 hours i.e. 13.8857 mpy, on aquades with a time of soaking 336 hours i.e. 16.5362 mpy and 504 hours 10.2385 mpy. While the results of the rate of low-carbon steel corrosion by cathodic protection anodes tumbal (zinc) in polluted water waste at the time of soaking 336 hours i.e. 5.872 mpy and 504 hours mpy 4.1158, on aquades with a time of soaking 336 hours i.e. 11.8512 mpy and 504 hours i.e. 9.1756 mpy. From the data analysis of the percentage decline in the rate of corrosion on unprotected water tercamar sampahmampu decrease by 28% and aquades 71%, while the percentage decrease in the rate of corrosion by cathodic protection anodes tumbal (zinc) are able to lower the rate of corrosion low-carbon steel in waste water tercemr aquades 66% and 17%.
