Materials degradation refers to the process by which materials lose their properties over time due to environmental factors, mechanical stress, or chemical reactions. This can occur in various materials, including metals, plastics, and ceramics, leading to reduced strength, durability, and functionality. Common causes of degradation include corrosion, oxidation, and fatigue. Preventing materials degradation is essential in many industries, such as construction, manufacturing, and electronics. Techniques like coating, alloying, and regular maintenance can help extend the lifespan of materials. Understanding the mechanisms of degradation allows engineers and scientists to develop better materials and protective measures to ensure safety and reliability.
