Surface coating
A high-quality coating can significantly increase the service life of components. For good adhesion, uniform application and resistance of the layer to various environmental influences, the components are mechanically and / or chemically pretreated before coating.
The selection of the manufacturing process for coating depends on the base material. OT Schwerin offers the following coating processes:
Diffusion coatings (CVD)
- Chromation in the packing process
- Alitation in the packing process
- Alitation with slurry
Compressor coating
- Coating of individual blades, compressor impellers and guide disks with special aluminum-pigmented ceramics via manual atmospheric spraying
- Hot coating of compressor shafts (new construction / service)
- Anti-fouling coating with Teflon (PTFE)
Thermal spray
- MCrAlY (metallic corrosion / oxidation protection layer) via high-speed flame jet spraying (HVOF)
- TBC coating with ceramic thermal insulation layers via APS
- Running-in layer (abradable coating)
- Antifretting (copper, nickel, indium coating) in connection with molybdenum disulfide application via APS
