Titanium Nitride (TiN)

TiN is the classic golden PVD coating for tooling—proven, versatile, and cost-effective. With HiPIMS, TiN becomes significantly more capable: denser, smoother, and with fewer defects.

HiPIMS: high-performance PVD coatings
RUBIG HiPIMS system in the coating center – high-performance PVD coatings

RUBIG is expanding its PVD portfolio with HiPIMS (High Power Impulse Magnetron Sputtering) – a state-of-the-art sub-variant of magnetron sputtering. The core: a latest-generation HiPIMS generator delivers pulse currents of up to 1000 A at 1200 V. The extremely high plasma density increases the ionization degree of the sputtered species to over 90% – comparable to arc evaporation, yet with very few defects. The result is very smooth surfaces and highly densified, hard coating systems with excellent wear and corrosion protection.

What Makes HiPIMS So Special?

RUBIG HiPIMS PVD process in the coating center – plasma inside the vacuum chamber

In HiPIMS, the sputter targets are pulsed with very high power for short periods. This generates a plasma with an exceptionally high ion content. The ionized coating material is precisely accelerated toward the workpiece, resulting in:

  • Significantly higher coating density (minimized porosity)
  • Superior adhesion (intensive surface activation)
  • Increased hardness and smoother topography (very low defect density)

Titanium Nitride (TiN) – the “golden” all-round coating

Typical toolmaking applications – HiPIMS coatings by RUBIG

Take it to the next level

TiN is the classic golden PVD coating for tooling: proven, versatile, and cost-effective. With HiPIMS, TiN delivers a clear performance boost—denser microstructure, fewer defects, and a much smoother surface.

Standard TiN vs. HiPIMS TiN: Microstructure & Hardness

Thanks to the high ionization in HiPIMS, TiN forms a highly densified microstructure (minimized porosity). This results in:
  • Fewer defects → higher process reliability under load
  • Very dense, fine-grained structure → improved barrier performance, fewer micro-chips
  • Smooth surface topography → lower friction, better edge protection

Hardness: Standard TiN vs. HiPIMS TiN

  • Standard TiN: typically around 2300 HV (depending on process/manufacturer)
  • HiPIMS TiN: depending on parameter settings, up to ~3000 HV possible – due to higher densification and improved microstructure

The coating properties stated were achieved under ideal deposition conditions. Depending on surface condition, component size, substrate material, and other process factors, properties on the actual part may differ.

  • Micro end mills / micro drills: very smooth coating, edge stability for fine geometries
  • Indexable inserts: dense structure, reduced abrasive and adhesive wear
  • General machining (steel, non-ferrous metals): lower friction, more stable tool life
  • Forming tools: less galling (cold welding), improved part surface finish
