Types of Corrosion Situations
External corrosion occurs on the outer surface of a structure, while internal corrosion takes place within the material. Good design practices can prevent such situations from occurring.
External corrosion
External corrosion occurs when a material deteriorates due to environmental factors such as moisture, oxygen, and pollutants. It can affect metal structures exposed to the atmosphere or buried in soil.
For instance, pipelines and outdoor equipment are susceptible to this type of corrosion. Understanding the mechanisms and preventive measures for external corrosion is crucial for corrosion engineers to ensure the durability and safety of various industrial structures.
Corrosion engineering encompasses extensive knowledge about different types of corrosion situations including external corrosion. By studying these occurrences, engineers develop strategies that enable them to mitigate risks associated with external corrosion effectively.
Internal corrosion
Internal corrosion occurs within the structure of a material. It can lead to weakening and eventual failure of pipelines, tanks, and other equipment used in industries like oil and gas.
The presence of water combined with corrosive agents causes internal corrosion which can be prevented by using protective coatings on the inside surface or employing chemical treatments to minimize the risk.
For instance, cathodic protection systems are widely used in underground pipelines to mitigate internal corrosion challenges effectively.
Good design to prevent corrosion situations
To prevent corrosion situations, good design plays a critical role. It involves the careful selection of materials with resistance to corrosion, such as stainless steel or galvanized coatings.
Additionally, controlling the environment where the material is placed can significantly reduce the risk of corrosion. This may include protecting structures from exposure to moisture or installing protective barriers to limit contact with corrosive substances.
Moreover, using coatings and corrosion inhibitors can provide an extra layer of protection against corrosive elements, extending the lifespan of materials and structures.
Preventive Measures
To prevent corrosion, it is essential to carefully select the right materials for construction and engineering projects. Controlling the environment, using corrosion inhibitors, and applying coatings are also effective preventive measures.
Material selection
Corrosion engineers choose materials based on their resistance to corrosion. They consider factors like the environment and potential corrosive agents. By selecting appropriate materials, they can prolong the lifespan of structures and equipment, reducing maintenance costs and increasing safety.
The proper material selection is crucial in preventing corrosion-related failures in industries such as oil and gas, infrastructure, and manufacturing.
Controlling the environment
Corrosion engineers control the environment to prevent corrosion experiences. They consider factors like temperature, humidity, and chemical exposure. Material selection plays a key role in controlling the environment as it directly impacts corrosion resistance.
The use of coatings and inhibitors further enhances protection against corrosion, reducing maintenance needs and extending material lifespan.

Use of corrosion inhibitors
In addition to controlling the environment, corrosion engineers also utilize corrosion inhibitors as a preventive measure. Corrosion inhibitors are substances that can slow down or prevent the corrosion of metals.
They work by forming a protective layer on the metal surface, acting as a barrier against corrosive elements. Common examples of corrosion inhibitors include organic compounds like amines and mercaptans, as well as inorganic compounds such as chromates and phosphates.
By incorporating these inhibitors into the design and maintenance of structures and materials, students studying corrosion engineering can contribute to the preservation and durability of various industry components.
Use of coatings
Corrosion engineers use coatings to protect materials from corrosion. These coatings act as a barrier, preventing moisture and other corrosive elements from reaching the underlying material.
Coatings can be applied through processes like painting, plating, or chemical treatments to enhance the resistance of metals and structures against corrosion. Understanding the right type of coating for different environments is crucial in preventing premature deterioration of materials.
Moving on from preventive measures, let’s delve into practical applications with some notable contributions in corrosion engineering.
