Composite Materials

Multifunctional Coatings 

  • 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
  • Monolayer vitro ceramic coatings, related to functional conditions of turbo engines for "hot parts"protections
  • Mono and multilayer protections, from complex alloys, resistant at temperature, corrosive and erosive wear, liquid metal contact,related to vital components from metalllurgy – tuyeres,lance tips,etc.
  • Duplex antifriction layers for realization of sliding journal for rolling mills up to 2000 mm diameter
