8.1 Introduction

Corrosion is the deterioration of metals caused by interaction with corrosive aqueous environments (air, moisture, or soil) and the formation of noble compounds as a consequence of a direct chemical or electrochemical reaction [1, 2]. Corrosion has caused death and damage expenditures in almost every technical profession throughout the years [3]. As a result, it is seen as a potentially catastrophic environmental concern, necessitating ongoing study toward a permanent remedy [4]. Corrosion is an ecological issue that has cost-effective, environmental, and safety implications ...
