In surface erosion, the polymer degrades from the exterior surface. The inside of the material does not degrade until all the surrounding material around it has been degraded. [1] In bulk erosion, degradation occurs throughout the whole material equally. Both the surface and the inside of the material degrade. [1]
Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable.
The process of biodegradation is threefold: first an object undergoes biodeterioration, which is the mechanical weakening of its structure; then follows biofragmentation, which is the breakdown of materials by microorganisms; and finally assimilation, which is the incorporation of the old material into new cells.
One can differentiate abiotic decomposition from biotic decomposition (biodegradation); the former means "the degradation of a substance by chemical or physical processes", e.g., hydrolysis; the latter means "the metabolic breakdown of materials into simpler components by living organisms", typically by microorganisms.
Wood degradation is a complex process influenced by various biological, chemical, and environmental factors. It significantly impacts the durability and longevity of wood products and structures, necessitating effective preservation and protection strategies.
Degradation (telecommunications), of an electronic signal; Biodegradation of organic substances by living organisms; Environmental degradation in ecology; Land degradation, a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land; Polymer degradation, as plastics age
It is the gradual deterioration of materials (usually a metal) by chemical or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and preventing corrosion. [1] [2] Riveted connection of elements of the cooling tower of a power plant from 1904. Increased material volume caused by corrosion.
