Utilization of Graphite Bars on Used Batteries Become Coating Material for Steel

Abstract

The purpose of this research is to utilize graphite rods in use batteries to be processed into graphene oxide as a coating on steel to be resistant to corrosion. Liquid exfoliation and surfactant methods used to make Corrosion Penetration Rate (CPR) method for calculating weight loss. Corrosion monitoring by immersing samples of low carbon steel in a solution of 0.1 M NaCl for 2, 4, and 6 hours. Final results showed that low carbon steel samples have CP R values that have the smallest CPR is 0.5 gram graphite bars on using batteries + 25ml aquadest + 25ml H 2 SO 4 . The value of not exceeding the standard permissible rate (0.5 mm/ yr). Applications for this study showed that CPR of low carbon steel that coated using graphene oxide from graphite bars on using batteries more lower than CPR of steel with a coating in general (galvanized).
