Polierte

Polierte is a German term with two main grammatical uses. It is the simple past tense form of the verb polieren (to polish), as in Er polierte die Münze. It is also the attributive form of the adjective poliert, used to describe a noun, especially in feminine singular or plural, such as eine polierte Oberfläche or polierte Metallteile.

In technical and design contexts, polierte describes surfaces or objects that have undergone a polishing process to achieve a smooth, often mirror-like finish. Polished surfaces are characterized by low roughness and high specular reflectivity. In manufacturing, a polierte finish is common for optics, precision mechanics, jewelry, metal components, and semiconductor devices. Methods include mechanical polishing, chemical polishing, and chemical-mechanical polishing (CMP). The choice of method depends on material, required surface roughness, and tolerance.

Quality and measurement: Surface roughness is typically quantified by metrics such as Ra or Rz, with polished finishes often specified by target values. Depending on the application, polished surfaces may reach nanometre to micrometre roughness levels and are evaluated for uniformity and defects.

Etymology and usage notes: Polierte reflects its roots in polieren and poliert, and appears in product descriptions, technical specifications, and dictionaries. It may function as both a verb past tense form and an adjective describing the finish of a surface.
