Cutting Tools and Wear Resistance:
- CrN is used as a coating for cutting tools (drills, end mills, inserts) to enhance wear resistance, reduce friction, and prolong tool life.
- Ideal for dry machining and semi-dry machining, where lubrication is limited.
Mold and Die Coating:
- Used in injection molding, die casting, and metal forming tools to improve performance and reduce sticking/wear.
Medical Instruments:
- CrN’s biocompatibility and corrosion resistance make it suitable for surgical instruments and dental tools.
Automotive Industry:
- Employed in engine components, piston rings, and other parts requiring hard-wearing surfaces.
Decorative Coatings:
- Used for watches, eyeglasses, and architectural hardware due to its aesthetic silver appearance and scratch resistance.
Aerospace Applications:
- Applied to components requiring high wear and oxidation resistance under high-temperature environments.
