Assignment # 2
Corrosion of Metals
Table of Contents
Assignment Question
Discuss the process of corrosion of metals, the various forms of corrosion and the implications (technical, economic, social, etc.) of corrosion in current society both locally and on a worldwide scale.
Introduction
Corrosion is defined as the degradation of materials by chemical interaction with their environment. Degradation implies the deterioration of physical properties of the material. The materials can be either polymers, ceramics, composite – mechanical mixtures of two or more materials with different properties or very often metals.
Humans have been trying to fully understand and subsequently control the corrosion process for as long as they have been using metal objects; which translates into a very long time since the most important periods of prerecorded history are named for the metals that were used for tools and weapons in those eras (Iron Age, Bronze Age).
In modern society corrosion still continues to be a nuisance, causing between $8 billion and $128 billion in economic damage per year in the United States alone, degrading structures, machines and containers. In order to control or minimize this kind of loss, a detail insight into the process ought to be obtained.
The content of this assignment focus on metal corrosion and seeks to highlight details into the process. It goes on to emphasize the various forms of corrosion as well as giving implications of it into the current society in an attempt to gain a better understanding of the process and its effects worldwide.
Overview
Derived from the Latin word ‘corrosus’ meaning eaten away, Corrosion is a thermodynamically spontaneous phenomenon that cannot be prevented.
