Question

Quizplus · Accepted Answer

Passivation is indeed a process where a material becomes less affected by environmental factors such as air or water by forming a protective coating, and aluminum is known for naturally forming an oxide layer that protects it from further corrosion. Steel rust, on the other hand, is not a form of preservation but rather a form of corrosion that deteriorates the metal.
