Ablation

Ablation near the electrode in a flashtube. The high-energy electrical arc slowly erodes the glass, leaving a frosted appearance.

Ablation (Latin: ablatio – removal) is the removal or destruction of something from an object by vaporization, abrasion, erosive processes, or other means. The object may be fully ablated away. Examples of ablation as it is relevant to various industries are described below, including spacecraft material for ascent and atmospheric reentry, ice and snow in glaciology, biological tissues in medicine, and passive fire protection materials.
