What is meant by the term 'material degradation'?

The term 'material degradation' refers to the deterioration of material properties over time due to various factors such as environmental conditions, use, or chemical interactions. This process can lead to a decline in performance, strength, and functionality of the material, making it less effective in its intended application.

For instance, metals can corrode when exposed to moisture and oxygen, while polymers may become brittle when subjected to UV light over extended periods. Understanding material degradation is essential for predicting the lifespan and reliability of materials in different settings, as well as for implementing proper maintenance and protective measures to mitigate the effects of degradation.

The other definitions do not align with the concept of material degradation. Improvement or enhancement implies that properties are increasing rather than deteriorating, and the idea of enrichment does not accurately reflect the loss of structural integrity or functionality typically associated with degradation.
