- 1. PRESENTED BY : BOUABDALLAH ABDELHAKIM CORROSION AND ITS CONTROL
- 2. SUMMARY Definitions Reason for Studying Corrosion Corrosion Control Conclusion
- 3. Corrosion, refers to the degradation or deterioration of a material, typically a metal, due to chemical or electrochemical reactions with its environment. This process often results in the loss of material, weakening of structural integrity, and alteration of physical properties.
- 4. Economic Impact: Corrosion causes significant economic losses worldwide, estimated to be billions of dollars annually. Corrosion has a big financial impact worldwide, costing over $2.5 trillion every year according to NACE International. This is about 3-4% of the entire global economy. These costs include things like preventing corrosion, fixing things that are corroded, and replacing equipment. It affects many industries, like oil and gas, transportation, and infrastructure. Besides direct costs, there are also other expenses like cleaning up the environment and losing productivity. So, it's really important to use good methods to control corrosion and avoid these losses.
- 5. Materials Development: Understanding corrosion mechanisms contributes to the development of new materials that are more resistant to corrosion.
- 6. Risk Management: Identifying and assessing corrosion risks is crucial for industries to maintain operational efficiency and safety.
- 7. Safety Concerns: Corrosion can compromise the structural integrity of materials, leading to catastrophic failures in critical infrastructure such as bridges, pipelines, and aircraft.
- 8. Safety Concerns: On December 15, 1967, the Silver Bridge connecting Ohio and West Virginia over the Ohio River collapsed, and 46 people lost their lives. The cause of the collapse was stress-corrosion cracking

Corrosion Control Material selection Inhibitors Design Cathodic protection Coatings Material selection for corrosion control is crucial for ensuring durability and safety in engineering systems. Factors such as corrosion resistance, environmental conditions, compatibility, mechanical properties, cost, and adherence to standards guide engineers in choosing the most suitable materials. This careful selection process helps mitigate corrosion risks, ensuring the long-term performance and reliability of structures and equipment
- 16. Corrosion Control Material selection Inhibitors Design Cathodic protection Coatings The design of a structure is frequently as important as the choice of materials of construction. Design should consider mechanical and strength requirements together with an allowance for corrosion Corrosion prevention must start at the blackboard, at the design stage. A good design at the backboard is no more costlly than a bad design, a bad design is always more expensive than a good design in reality.
- 20. Corrosion Control Material selection Inhibitors Design Cathodic protection Coatings Corrosion inhibitors are substances or compounds that are added to a corrosive environment to reduce the rate of corrosion on metal surfaces. These inhibitors work by forming a protective layer on the metal surface, which acts as a barrier between the metal and the corrosive environment, thus slowing down the corrosion process
- 21. Studying corrosion is really important because it helps us understand how things like pipelines, refineries, and other structures deteriorate over time. By figuring out how corrosion happens and finding ways to stop it, we can make our infrastructure stronger and safer. This not only saves money but also helps protect the environment and keeps people safe. So, it's essential to learn about corrosion to make our world more sustainable and resilient.
