Abrasive comes from the term Abrasion (from Latin abrasio , Scraping '). The abrasion describes the removal of a material by rubbing or grinding. If a material is described as abrasive, it has a rubbing or dragging effect, which in turn has a smoothing, cleaning or wiping effect. Abrasives are therefore also known as abrasives.
In the preparation of the coating process, most of the parts are sandblasted (engl. sandblasting, abrasive blasting). This is an abrasive process because compressed air is "fired" on the part by compressed air to remove the topmost layer of the part.
Coatings can be particularly resistant to abrasion, which means that the coating is very resistant to abrasion or scratching. Parts exposed to high levels of abrasive wear are coated with a particularly abrasion-resistant coating to protect them from abrasion and to increase the life of the component.
Also, a coating may have abrasive features, which is then not used as abrasives or abrasives, but the rough properties are in the foreground, z. B. to achieve a slip-resistant effect.
