Effect of Temperature on the Rate of Corrosion of Mild Steel in Acidic and Basic Environments

CHAPTER ONE

1.1 Background to the Study

Corrosion is a significant problem affecting the durability and structural integrity of metals. Mild steel, widely used in construction and manufacturing, is prone to corrosion when exposed to acidic or basic environments. Temperature is one of the key factors influencing the rate of corrosion by affecting reaction kinetics and metal reactivity (Fontana, 2017). Understanding how temperature affects corrosion behavior helps in developing preventive measures and selecting appropriate materials for industrial use.
Corrosion leads to economic losses, safety hazards, and environmental damage, making its study important in both academic and industrial contexts (Uhlig & Revie, 2018).

1.2 Statement of the Problem

Although corrosion mechanisms are well understood, limited data exist on how temperature variations affect the corrosion rate of mild steel in both acidic and basic media. This knowledge gap affects industrial material selection and protection strategies.

1.3 Objectives of the Study

1. To investigate the effect of temperature on the corrosion rate of mild steel.

2. To compare corrosion behavior in acidic and basic environments.

3. To identify the temperature range where corrosion is most aggressive.

1.4 Significance of the Study

The results will help industries design effective corrosion prevention methods and select appropriate materials for high-temperature environments. It also adds valuable information to corrosion science, aiding in predictive modeling of metal degradation.

1.5 Scope of the Study

The study will be limited to laboratory experiments involving mild steel samples immersed in controlled acidic and basic solutions at varying temperatures.
