Final answer:

Galvanic corrosion can be prevented through protective coatings, cathodic protection, and preventing contact with oxygen and water.

Step-by-step explanation:

Galvanic corrosion can be prevented through various methods:

  1. Protective coatings: Applying a second metal coating that is more difficult to oxidize than the metal being protected, such as galvanizing steel with a layer of zinc.
  2. Cathodic protection: Attaching sacrificial electrodes made of a more easily oxidized metal, such as zinc or magnesium, to the object being protected.
  3. Preventing contact with oxygen and water: Using paint, grease, plastic, or other coverings to prevent the metal from coming into contact with oxygen and water.
