T Coat

T Coat (TOYO, T Coat)

This highly lubricating coating is formed at temperatures of 180°C or less—quite low for the PVD method—and has excellent adhesion resistance.

Features
Typical Applications

  • This shows excellent adhere resistance and overwhelmingly low friction co-efficient.
  • This gives high lubricity on parts or die surfaces resulting in significant reduction of the lubricating oil.
  • Higher performance is available via multiple coating with conventional coating film.
  • Tools, dies or parts used without lubricant
  • Heavy high stamping (for high-tension steel plates, plated steel plates or stainless steel materials)
  • High-load cold forging

Application example for burring process

Shot numbers are compared in burring process by 'TiC coated' punch and by 'TiC + T Coated' punch.

Process Conditions Results

  • Die : Burring punch
  • Stamped material: 600MPa strength class
  • Plate thickness: 2.8mm
  • Base metal: SDK11
The combination 'TiC + T Coated' punch has a 5 times longer life than the 'TiC' only punch.

The T Coat coating with overwhelmingly low friction co-efficient shows excellent adhere resistance and can extend its life further.
