Plasma Spray Coatings
Effective coating solutions require an on-going commitment to research & development and state-of-the-art equipment. This approach has been a key element in the growth of VAC AERO’s coating operations provided to the aerospace and commercial sectors. The complex problems of oxidation and corrosion protection for components that are exposed to harsh service environments require solutions that use the correct combination of coating material and application technique. VAC AERO coating solutions are used in both new part applications and for restoration of service damaged components. Thermal spray coatings are applied using robotically-controlled manipulators for maximum coating integrity. VAC AERO Kalisz offers:
- Air-plasma spray coatings
- Pack aluminide coatings.
COATING APPLICATIONS:
- Dimensional Restoration and Pure metals and alloys,
- Wear Resistance Tungsten carbides for electrolytic hard chrome replacement and for higher temperature environments,
- High Temperature Protection, and Diffused Aluminide for oxidation and hot corrosion protection,
- Clearance Control Low temperature abradables: Ni/Graphite, Al/Polyester,
- High temperature abradables.
