Description
In a material or work of art, a loss defined as the absence of a component. Loss may occur through chemical or mechanical actions. The primary chemical action resulting in loss is corrosion. Mechanical forces may be divided into: erosion, abrasion, and wear.
- Erosion involves impingement (impact) of solid or liquid particles in a fluid (e.g., liquid) onto a surface
- Abrasion involves interaction between the surface and hard solid particles normally in one direction
- Wear involves relative motion (rubbing) between the surface and another solid substance in more than one direction
When there is a combination of degradation actions, such as corrosion and abrasion, combined effect may be more severe than sum of all individual effects.
