TAF Coat

Improve the ability to retain the lubricating oil to improve the surface of the adhesion film

A fully new surface reforming coating which can improve the performance of conventional coating considerably.

  • Features

  • Coating film adhesion can be further improved by multiple coating with conventional coating film.

  • Damage of die base metal is restrained by removing the causes of wear points through smoothing the surface of base metal.

  • Lubricant runout is decreased by lubricant holding effect.

  • Typical Applications

  • Heavy ironing (stamping for high-tension / stainless steel materials)

The Ring-on-disc type friction wear test [Why the TAF Coat is strong]

Pressing a ring made of AISI-1045 on rotating discs coated by 'TiC' or 'TiC + TAF Coat', the time was measured until a galling happens on the disc.

Test Method

Test Conditions

  • Speed of rotation: 140 rpm (10m/min)
  • Pressure force: 0.75 kg/cm² (150kgf)
  • No lubrication

Results

The friction co-efficient of the 'TiC + TAF Coated' disc was reduced approx. two-thirds.
Therefore, it took twice as long as before for a galling to happen.

Application guidance

We accept your order with a set of coating film of conventional lineup.

For example
  • Combination of TAF Coat and CVD such as TiC, C-TiCN or CrC;
  • Combination of TAF Coat and PVD such as TiN, P-TiCN or CrN.
