New Materials
Multilayer ceramic micro and nano structured, resistant at temperatures, thermal shock, corrosive and erosive wear, fretting corrosion,etc. applied at turbo engines and modern co generative systems
 |
Modern TBC ’s are in fact, a complex coating system of multiple layers using complicated and expensive materials and multistage processes of coating, composition, morphology and microstructure Basic configuration of a multilayer TBC system observed in cross-section by scanning electron microscopy |
