Applied Chemistry I: UNIT 4: Corrosion and Control
Corrosion and Control: Introduction
Corrosion is defined as the gradual destruction or deterioration of metals or alloys by the chemical or electrochemical reaction with its environment.
Unit ‒ IV
Corrosion and Control
INTRODUCTION
Metals and alloys are
generally used as fabrication or construction materials in engineering. If the
metal or are not properly maintained, they alloy structures are deteriorate
slowly by the action of atmospheric gases, moisture and other chemicals. This
phenomenon of deterioration or destruction of metals and alloys is known as
corrosion.
Definition
Corrosion is defined as
the gradual destruction or deterioration of metals or alloys by the chemical or
electrochemical reaction with its environment.
Consequences (or) Effects of Corrosion
1. Due to formation of
corrosion product over the machinery, the efficiency of the machine gets lost.
2. The products get
contaminated due to corrosion.
3. The corroded
equipments must be replaced frequently.
4. Plant gets failure
due to corrosion.
5. It is necessary for
over design to compensate for the corrosion.
6. Corrosion releases
toxic products, health hazard, etc.
7. Time is lost in
making available parts.
8. The value of the goods is reduced.
