Mikrotexturierte

Mikrotexturierte describes surfaces that have deliberately introduced textures with micrometer-scale features. The term is used in materials science, tribology and surface engineering to denote a controlled microtexture produced on metals, polymers, ceramics and coatings to modify surface interactions.

Common feature sizes range from a few hundred nanometers to tens of micrometers, depending on the application. Microtextures influence properties such as friction, wear resistance, lubrication retention, wettability and optical appearance by altering how surfaces contact and interact with liquids, air and other solids.

Production methods include laser texturing, chemical or electrochemical etching, micro-embossing and imprinting, mechanical texturing, and additive manufacturing. The choice of method affects texture geometry, distribution and durability, as well as manufacturing-related costs and feasibility.

Applications span automotive components (piston skirts, bearings), cutting tools, medical implants, consumer electronics and sports equipment. Mikrotexturierte surfaces can reduce adhesive wear, promote controlled lubrication, improve anti-icing or anti-fouling performance, and tailor light scattering or color.

Characterization uses profilometry, scanning electron microscopy and optical methods to quantify texture parameters such as roughness and feature size. The design of mikrotexturierte surfaces requires balancing performance goals with manufacturing cost, durability and scalability.
