Why EB-PVD for Turbine Blade Coating?

- Lowering temperatures of hot section components of aero engines exposed to high-temperature combustion
- Protection against oxidation & corrosion caused by high-temperature gas
- Allows increased working temperature of turbine
- Increased efficiency of turbine
- Extended lifetime of components
- Characteristic columnar structure of EB-PVD coatings by optimized combination of process parameters: temperature, rotation speed, coating rate, process gas


Substrate handling by superior substrate feeder concept providing full programmable rotation and tilting of components during coating
Thermal radiation heating in fully insulated heater structure – rapid heating at excellent uniformity of up to 1200 °C
High-rate electron beam evaporation of TBC layers from ceramic ingots due to industry-leading electron beam equipment
Superior maintenance concept for short downtimes
Flexible design layout: single-sided / dual-sided feeding
Advanced coating options: single-material / dual-material coating
