Hello, myself Tanvir Alam Joy. As a chemical engineering student, I have to prepare some pptx slides for our project so I would love to share those with you since Slideshare helped me a lot to find various data.

5. UniformCorrosion
Our Topic

6. CORROSION

7. CORROSION
Degradation or destruction of metals or alloys due to chemical or electro chemical
reaction with the surrounding environment

8. TYPES

9. TYPESOFCORROSION
 GalvanicCorrosion
 Uniform Corrosion
 Pitting Corrosion
 Stress Corrosion
 Aqueous Corrosion
 So on….
 Dry Corrosion
 Wet Corrosion

11. UNIFORMCORROSION

12. UNIFORMCORROSION
 Also known as general corrosion
 A type of corrosion attack that is more or less uniformly distributed over the entire exposed
surface of a metal

13. 0
Rusting of Iron Chain
Some Examples
In Heat Exchanger In Distillation Column In Structural Steels

14. MECHANISM

20. PREVENTION

21. PREVENTION
 Use thicker materials for corrosion allowance
 Use paints or metalliccoatings such asplating, galvanizing or anodizing
 Use Corrosion inhibitors
 Cathodic protection and Anodic Protection

22. FACTS

23. FACTS
 Most well known corrosion type
 Rates of uniform corrosion are expressed as a mass loss per unit area and unit
of time
 Uniform corrosion on stainless steel occurs mostly with exposure to strong
acidor hot alkalineenvironments
