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).
ph值和含水率对外加电流阴极保护电流密度的影响:响应面方法学研究
本研究是基于外加电流阴极保护(ICCP)中的阴极保护这一腐蚀控制方法。本研究的目的是探讨pH值和含水率对碳素钢管ICCP腐蚀电流密度的影响。影响腐蚀电流密度的因素包括pH值和土壤含水量。本研究将采用design - expert 6.0.6软件,通过面心中央复合设计(FCCCD),采用单因素一次法(OFAT)和响应面法(RSM)研究这些变量对电流密度的影响。本研究的结果通过方差分析(ANOVA)进行分析,并通过图形、方程和建模(响应面图(三维图- 3d)和等高线图(二维图- 2d)来说明电流密度变量之间的相互作用。
