Vacuum coating
Vacuum coating is a process in which thin layers of materials are applied to surfaces under vacuum conditions.
Typical methods of vacuum coating are physical processes such as PVD (Physical Vapor Deposition) and chemical processes such as CVD (Chemical Vapor Deposition). In PVD processes, the material is usually transferred to the substrate by evaporation or atomization (sputtering).
The NEOVAC team has decades of experience with the various methods of vacuum coating. In addition to the generally known conventional processes such as magnetron sputtering, vapor deposition and vapor jet technology, NEOVAC has developed a new type of process.
The Plasma Enhanced Evaporation is the result of decades of experience and combines the high coating rate of vapor deposition with a coating quality that can be specifically influenced. Thanks to Plasma Enhanced Evaporation the Zn-PVD coating properties can be adapted to the requirements of the respective substrate material.
Vacuum coating has been an established coating technology for decades and is used in numerous industries. It is suitable for the production of metal coatings, ceramic coatings or special functional coatings, e.g. for corrosion protection.
The advantages of vacuum coating are manifold:
- Precisely controllable coating conditions
- Extremely even layers with high adhesive strength
- Precisely controllable layer thicknesses
- Excellent surface quality
- very pure layers, without chemical reaction with foreign atoms
- Wide variety of materials, including composite materials
- Gentle coating due to low substrate temperature
In addition, vacuum coating is an extremely environmentally friendly process due to its excellent energy efficiency and economical use of materials.
Due to these advantages, vacuum coating has been an indispensable process in modern production technology for decades.
