Patent Category: 

Overview: 

Nanocrystalline titanium carbide [TiC) powders are synthesized from corresponding elemental constituent powders by reaction milling in a specially designed dual drive planetary mill at room temperature with any prior and post heat treatment.

Key Features: 

  • Percentage yield of titanium carbide is significantly more in lesser milling time.
  • Room temperature synthesis [no external heating source is required].
  • Ultra-fine nanostructured powders can be prepared, (<10 micron).
  • No atmosphere control during synthesis is required.
  • Process is economical,time efficient and scalable.
  • This syntesis process co-friendly.

Applications: 

  • The material is extremely hard and can be used as good coating material for scratch proof and wear resistant coatings.
  • Potential coating material for coatings on tungsten carbide cutting tools.
