Turbine Blade CoatingWith Modular and Reliable Equipment

and superior electron beam technology

Why EB-PVD for Turbine Blade Coating?

Purpose

Lowering temperatures of hot section components of aero engines exposed to high-temperature combustion
Protection against oxidation & corrosion caused by high-temperature gas

Effect

Coating Quality

Characteristic columnar structure of EB-PVD coatings by optimized combination of process parameters: temperature, rotation speed, coating rate, process gas

OUR FLAGSHIP

barrier coating

value proposition for thermal barrier coating

EB-PVD Coater Concept

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
