    Factors which influence metal corrosion and the rate of corrosion are ____.

    • Biological organisms and concentrations of electrolytes

    • Availability of oxygen and time

    • Type of metal and temperature

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    The factors that influence metal corrosion and the rate of corrosion are biological organisms and concentrations of electrolytes, availability of oxygen and time, and the type of metal and temperature. Biological organisms and electrolyte concentrations can accelerate corrosion by providing a conducive environment for chemical reactions. The availability of oxygen is necessary for the oxidation process that causes corrosion, and the duration of exposure to these factors determines the rate of corrosion. Additionally, different metals have varying susceptibility to corrosion, and higher temperatures can accelerate the corrosion process. Therefore, all of these factors contribute to metal corrosion and its rate.

    Correct Answer
    A. Both A and B
    Explanation
    The buildup of pollutants, dust, and debris can degrade ESD shielding by promoting corrosion and acting as insulators. Pollutants, dust, and debris can cause corrosion on the ESD shielding material, which weakens its ability to conduct electricity effectively. Additionally, these particles can act as insulators, preventing the proper flow of electricity and reducing the effectiveness of the ESD shielding. Therefore, both options A and B are correct.

    Rate this question:

  • 6. 

    The two most important factors in preventing corrosion are ____.

    • Removal of the electrolyte and the application of protective coatings

    • Bundling wires correctly and grounding all electrical equipment

    • Cleaning equipment daily and accurate reporting of damage

    A. Magnesium
    Explanation
    White, powdery mounds or spots are common corrosion by-products of magnesium. Magnesium is a highly reactive metal that easily reacts with oxygen and moisture in the air, forming a white powdery substance known as magnesium oxide. This corrosion process occurs when the surface of magnesium is exposed to the elements, leading to the formation of these characteristic white mounds or spots.

    Rate this question:

  • 12. 

    Blue or blue-green accumulations are common corrosion by-products of which alloy?

    • Silver

    • Copper

    • Cadmium

    • Aluminum

    Correct Answer
    A. Copper
    Explanation
    Blue or blue-green accumulations are common corrosion by-products of copper alloy. Copper is prone to corrosion, especially in the presence of moisture and oxygen. When copper corrodes, it forms a blue or blue-green patina on its surface. This patina is a result of the reaction between copper and the surrounding environment, forming copper oxide and copper carbonate. These corrosion by-products not only give copper its characteristic color but also act as a protective layer, preventing further corrosion of the metal. Therefore, the presence of blue or blue-green accumulations is a clear indication of copper corrosion.
