Flashcards on Durability and Corrosion
Click on the flashcard to see the answer
What is durability?
The ability of a material to withstand wear, pressure, or damage.
What is corrosion?
The gradual destruction of materials (usually metals) by chemical reaction with the environment.
What are the factors that can affect the durability of a material?
Factors such as chemical exposure, temperature, humidity, and mechanical stress.
What are the common types of corrosion?
Uniform corrosion, pitting corrosion, crevice corrosion, and galvanic corrosion.
How can corrosion be prevented?
By using protective coatings, alloys, cathodic protection, and proper maintenance.
What are some examples of materials with high durability?
Stainless steel, concrete, and certain polymers.
What are the negative effects of corrosion?
Loss of structural integrity, reduced functionality, and increased maintenance costs.
What is the role of corrosion inhibitors?
To reduce the rate of corrosion by forming a protective layer on the surface of the material.
What are some methods used to test the durability of materials?
Abrasion resistance test, impact test, and accelerated aging test.
How does temperature affect corrosion?
Higher temperatures can accelerate the rate of corrosion.
What is the impact of corrosion on infrastructure?
Corrosion can lead to the deterioration of bridges, buildings, and other critical structures.
What is the role of surface preparation in preventing corrosion?
Proper surface preparation can remove contaminants and improve coating adhesion, reducing the likelihood of corrosion.
What are some techniques used for corrosion monitoring?
Electrochemical methods, visual inspection, and non-destructive testing.
What are the advantages of using corrosion-resistant materials?
Longer lifespan, reduced maintenance needs, and cost savings.
How can corrosion impact the automotive industry?
Corrosion can cause structural damage to vehicles and affect their safety and resale value.
