Which of the following is not a type of corrosion?

  1. Uniform corrosion

  2. Pitting corrosion

  3. Crevice corrosion

  4. Erosion corrosion


Correct Option: D
Explanation:

Erosion corrosion is a type of wear, not corrosion.

What is the primary cause of uniform corrosion?

  1. Exposure to oxygen

  2. Exposure to water

  3. Exposure to acids

  4. Exposure to bases


Correct Option: A
Explanation:

Uniform corrosion is caused by the reaction of a metal with oxygen in the presence of water.

Which of the following metals is most resistant to corrosion?

  1. Iron

  2. Copper

  3. Aluminum

  4. Gold


Correct Option: D
Explanation:

Gold is the most resistant to corrosion because it is a noble metal.

What is the most common method of preventing corrosion?

  1. Painting

  2. Galvanizing

  3. Anodizing

  4. Cathodic protection


Correct Option: A
Explanation:

Painting is the most common method of preventing corrosion because it provides a barrier between the metal and the environment.

What is the process of degradation of materials due to chemical reactions?

  1. Corrosion

  2. Erosion

  3. Oxidation

  4. Wear


Correct Option: A
Explanation:

Corrosion is the process of degradation of materials due to chemical reactions with their environment.

What is the primary cause of pitting corrosion?

  1. Exposure to oxygen

  2. Exposure to water

  3. Exposure to acids

  4. Exposure to bases


Correct Option: C
Explanation:

Pitting corrosion is caused by the localized attack of a metal by an acid.

Which of the following is not a type of degradation?

  1. Corrosion

  2. Erosion

  3. Oxidation

  4. Wear


Correct Option: A
Explanation:

Corrosion is a type of degradation, but erosion, oxidation, and wear are not.

What is the process of degradation of materials due to mechanical forces?

  1. Corrosion

  2. Erosion

  3. Oxidation

  4. Wear


Correct Option: B
Explanation:

Erosion is the process of degradation of materials due to mechanical forces.

What is the primary cause of crevice corrosion?

  1. Exposure to oxygen

  2. Exposure to water

  3. Exposure to acids

  4. Exposure to bases


Correct Option: B
Explanation:

Crevice corrosion is caused by the localized attack of a metal by water in a crevice.

Which of the following is not a method of preventing degradation?

  1. Painting

  2. Galvanizing

  3. Anodizing

  4. Cathodic protection


Correct Option: D
Explanation:

Cathodic protection is a method of preventing corrosion, not degradation.

What is the process of degradation of materials due to exposure to high temperatures?

  1. Corrosion

  2. Erosion

  3. Oxidation

  4. Wear


Correct Option: C
Explanation:

Oxidation is the process of degradation of materials due to exposure to high temperatures.

Which of the following is not a type of oxidation?

  1. Rusting

  2. Tarnishing

  3. Patina

  4. Anodizing


Correct Option: D
Explanation:

Anodizing is a process of forming a protective oxide layer on a metal, not a type of oxidation.

What is the process of degradation of materials due to friction and abrasion?

  1. Corrosion

  2. Erosion

  3. Oxidation

  4. Wear


Correct Option: D
Explanation:

Wear is the process of degradation of materials due to friction and abrasion.

Which of the following is not a factor that affects the rate of corrosion?

  1. Temperature

  2. pH

  3. Concentration of reactants

  4. Presence of inhibitors


Correct Option: D
Explanation:

The presence of inhibitors is a factor that affects the rate of corrosion, not a factor that affects the rate of degradation.

What is the process of degradation of materials due to exposure to radiation?

  1. Corrosion

  2. Erosion

  3. Oxidation

  4. Radiation damage


Correct Option: D
Explanation:

Radiation damage is the process of degradation of materials due to exposure to radiation.
