Title:

Nano-composite Hard Coating
Value Proposition:

Synthesis of nano-composite coatings from powders of Borides and carbides of Ti, Si. Metallic Si powder, Argon and nitrogen IOLAR Grade 1
Summary Application:

The developed nano-compositeTi-Si-B-C coatings exhibit excellent mechanical properties, good tribological properties with low coefficient of friction. The coating also shows excellent resistance to chemical corrosion (salt spray 500 hrs, no degradation) and oxidation resistance up to 800°C.
Advantages:
  • Magnetron sputtering Hardness can be tailored.
  • 10-40 GPa Coefficient of friction.
  • 0.1-0.2, Nano-crystalline grain size in amorphous matrix.
