Vakuumschichten

Vakuumschichten, also known as vacuum deposition, is a process used to produce thin solid films on a substrate under vacuum conditions. This technique is employed to deposit a wide range of materials, including metals, alloys, ceramics, and polymers. The vacuum environment is crucial because it prevents contamination of the deposited film by atmospheric gases and allows for precise control over the deposition process.

There are several methods of vacuum deposition. Physical vapor deposition (PVD) involves the physical transfer of a source material to the substrate. Common PVD techniques include evaporation, where the source material is heated until it vaporizes, and sputtering, where ions are used to bombard a target material, ejecting atoms that then travel to the substrate. Chemical vapor deposition (CVD) is another major category, where a precursor gas reacts on or near the substrate surface to form the desired film.

The applications of vacuum-deposited films are extensive. They are used in electronics for creating conductive pathways and insulating layers, in optics for anti-reflective coatings and mirrors, and in metallurgy for enhancing the hardness and wear resistance of tools. In the field of nanotechnology, vacuum deposition is vital for fabricating intricate nanoscale structures. The ability to control film thickness down to the atomic level makes vacuumschichten a cornerstone of modern material science and manufacturing.
