Material degradation refers to the process by which materials lose their original properties over time due to various factors. This can occur through mechanisms such as corrosion, wear, and fatigue, often influenced by environmental conditions like moisture, temperature, and exposure to chemicals. Common examples of material degradation include rust forming on iron when exposed to water and oxygen, or the weakening of plastic due to prolonged exposure to UV radiation. Understanding material degradation is crucial for maintaining the integrity and safety of structures, vehicles, and everyday objects.
