abradiert

Abradiert is a German term used primarily in materials science and mechanical engineering to describe a surface that has undergone an abrasion process, resulting in material removal. The adjective describes the outcome of abrading a surface rather than the specific tool or method used. In practice, abradiert surfaces are prepared for further processing, for example to improve adhesion of coatings, to achieve a defined dimensional tolerance, or to remove burrs and contaminants.

The process of abradin g can be performed by various methods, including grinding, sanding, lapping, or abrasive blasting. The choice of abrasive material (such as aluminum oxide, silicon carbide, or ceramic grains), grain size, and exposure time determines the resulting surface texture and roughness. In quality control, the degree of abradiert surface is often specified by roughness parameters (for example Ra, Rz) and by cleanliness criteria relevant to the next manufacturing step.

In typical use, the term appears in passive constructions such as “Der Werkstoff ist abradiert” or “Die Fläche muss abradiert werden,” indicating that the surface has already undergone abrasion or must undergo it to meet specifications. Abradiert surfaces are contrasted with ground, polished, or milled surfaces, each terminology reflecting a different surface finish outcome.
