Physical and Mechanical Properties of FortiPhySM Chromium Nitride (CrN) Thin Film Tool Coating

Phygen produces ultra endurance coatings using our patented plasma acceleration process. The resulting nanocrystalline microstructure is extremely dense and uniform, for the toughest coatings possible. FortiPhySM coating’s key characteristics include:

  • Extreme hardness and toughness (reduced fatigue and other material breakdown)
  • High cohesive strength (unmatched adhesion)
  • Very low coefficient of friction (improved sliding, rolling, rotation, and release)
  • Excellent corrosion and abrasive wear resistance (longer useful life)
  • Low processing temperature (reduced dimensional, physical, or finish changes)
  • Inert (safer medical implants and prosthetics)
  • Approved for food contact (improved versatility in a variety of industries)

The following table details the physical properties of FortiPhy Chromium Nitride Coating as applied using Phygen's patented high-energy plasma process:
