Objective

Novel design of the turbo-engine rotor blades working at high temperatures

Novel coating applied to turbo-engine rotor blades working at high temperatures with the goal of extending their useful life

Specific objectives for INOE 2000:

v Novel coating applied to turbo-engine rotor blades of Ni alloy type NCK 18 TDA working at high temperatures, aiming to extending their useful life.

Results:

1. Multilayer Ti/TiN, TiAlN/Al₂O₃

2. Deposition processes: cathodic arc and reactive magnetron sputtering

3. Homologated coated rotors during their mounting on the engine at PETROM-SERVICE
