Abstract

This study is based on one of the corrosion control which is cathodic protection on impressed current cathodic protection (ICCP). The purpose of this study is to investigate the effect of pH and moisture content on corrosion current density of ICCP for carbon steel pipe. Several factors could affect the corrosion current density including pH and moisture content of the soil. This study will be conducted by investigate the effect of these variables on current density using one-factor-at-a-time (OFAT) method and response surface methodology (RSM) via face centered central composite design (FCCCD) using Design-Expert 6.0.6 software. The results of this study is analyses via analysis of variance (ANOVA) and used to illustrate the interactions between variables on current density by graphical, equation and modeling which are response surface plots (three-dimensional plots-3D) and contour plots (two-dimensional plots-2D).
