INTRODUCTION<br />
This chapter is to briefly explain the major information of whole project is carrying<br />
out. Overall, it summarized the progress of the whole project which describing on<br />
how the project has been done.<br />
1.1 Project Overview<br />
Generally, the main purpose of project is to investigate corrosion behavior of tool<br />
steel in tannic acid from the plant. The whole project is emphasis on composition of<br />
the cutting tool blade in tannic acids and how it affected by temperature, pH and<br />
concentration. The aim of this research is to characterize the corrosion behavior of<br />
different steels in various wood processing environments. To carry out this project,<br />
the understanding of characteristic of tannic acid and composition element in<br />
material are significant aspect.<br />
Moreover, the estimation method of corrosion data from Gamry Instrument<br />
Framework Software using Tafel Technique and Polarization Resistance method is<br />
very crucial. Before starting up with experiment, concentration of tannic acid and<br />
composition of sample require verify because different concentration of tannins will<br />
give different corrosion behavior.<br />
The experimental procedure of this project is divided into three main categories<br />
which are sample preparation, corrosion test and data analysis. This project was carry<br />
out via Tafel Technique and Polarization Resistance method by immerse the sample<br />
in different concentration and temperature of tannic acid. After sample preparation,<br />
