Abrasion

• Any injury which rubs off the surface of the skin.
• General wearing of a surface by constant scratching, due to the presence of foreign matter such as metallic particles grit, or dirt in the lubricant. It may also cause a break down of material (such as gears tooth's surfaces). Lack of lubrication may result in abrasion.
• Tiny nicks along facet junctions, producing white fuzzy lines instead of sharp crisp facet edges.
• a superficial rub or wearing off of the skin, usually caused by a scrape or "brush burn."
• Wearing or rubbing away of a part.
• Removal of tooth structure due to rubbing and scraping (eg incorrect brushing method)
• A form of mechanical weathering that occurs when loose fragments or particles of rocks and minerals that are being transported, as by water or air, collide with each other or scrape the surfaces of stationary rocks.
• The technique of grinding shallow decoration with a wheel. The decorated areas are left unpolished.
• A wearing of away of material by friction.
• Using something rough (such as sandpaper).
• A rubbing and wetting technique used on the surface of the garment to make it look worn or faded.. Pumice stones are used most frequently.
• frictional erosion by material transported by wind and waves See also: abrasion platform, erosion
• the process of particles rubbing against each other, wearing down the sharp edges into smaller pieces.
• to wear down by being rubbed against.
• The process in which one material (such as sand-laden water) grinds away at another (such as a stream channel’s floor and walls).
• General wearing of the surface, as a result of constant contact with foreign substances like dirt.
• Abnormal loss of tooth structure due to non-masticatory physical friction.
• It is the cause of the consumption of the tread and is determined by friction between the tread and the ground. It is heightened for instance by temperature increases, different pressure than the nominal one, etc.
• an abraded area where the skin is torn or worn off
• erosion by friction
• grinding: the wearing down of rock particles by friction due to water or wind or ice
• The act of abrading, wearing, or rubbing off; the wearing away by friction; The substance thus rubbed off; A superficial excoriation, with loss of substance under the form of small shreds; The effect of mechanical erosion of rock, especially a river bed, by rock fragments scratching.
