In Engineering, what does the term "degradation" primarily refer to?

The term "degradation" in engineering primarily refers to a reduction in quality. This concept encompasses a variety of processes whereby the performance, functionality, or reliability of a material or system diminishes over time. Degradation can occur due to various factors, such as environmental conditions, mechanical stress, chemical reactions, or fatigue.

When materials and systems degrade, they may lose their structural integrity, efficiency, or effectiveness, ultimately leading to failures or the need for repair or replacement. Understanding degradation is crucial in fields such as materials science, mechanical engineering, and manufacturing, as it informs maintenance schedules, material selection, and design considerations to enhance durability and longevity.
