SurfTech 3012 chromium nitride (CrN) PVD coating is the solution for coating blades, knives, ceramics, plastics and other materials that come in contact with food.  

SurfTech 3012 is one of the few FDA-approved surface coatings for repeat-use food processing and food packaging equipment to prevent abrasive wear to the components of the equipment. 

It is the only such coating to use SurfTech’s exclusive non-bias, low-temperature (below 200º F!) Ion-Assisted PVD coating process. With our PVD coating process, non-conductive and heat-sensitive materials such as ceramics and hardened steel can now be coated—extending the lives of these components.  

Chromium Nitride: A Hard, Corrosion-Resistant Coating 

SurfTech® 3012 is a hard lubricous coating. Chromium nitride is harder than other coatings such as Teflon and TiN. It also excels at resisting corrosion.  

It is applied at low temperatures (BELOW 200°F) at thicknesses of 1 – 3 µm using the same equipment as the other SurfTech® coatings. 

It extends the life of an uncoated component by 3-5 times. 

Keeps Blades Sharper Longer 

SurfTech 3012 is popular for coating blades used in food processing. SurfTech’s unique alternative PVD coating process keeps sharp edges sharp and removes the “teardrop” effect caused by the traditional PVD coating process. 

This unique coating has been used to coat: 

  • blades for cutting pasta, meat, fish, or shrimp 
  • wear components in food processing plants 
  • blades used in a corrosive environment (salt water) for corrosion resistance 
  • And more! 

Cost-Effective PVD Coating 

Its one-layer structure and quick run time make this one of SurfTech’s least expensive coatings.
