PVD Coatings

Does your implant or instrument require enhanced wear resistance?


The ultra-hard ceramic coating is applied utilizing a technology known as cathodic-arc physical vapor deposition (PVD).

This technique is conducted in a vacuum chamber, where an electric arc is used to vaporize metal targets (i.e. titanium) into a plasma field. The vaporized metal then reacts with a specified process gas and condenses on the device forming a thin, well adhered, ultra-hard ceramic coating. By tightly controlling the process parameters, outstanding reproducibility of the coating process can be achieved.

Our technologies are utilized on millions of devices every year, allowing us to contribute to improvements in the quality of life of patients worldwide.
The ultra-hard ceramic coating can improve the wear properties of both instruments and articulating implants, potentially increasing their functional life. The coating can also have aesthetic value, and some studies have shown the coatings to act as a barrier layer to potential allergic reactions to substrate material constituents.
Sample devices with a strong history of PVD coating utilization:

  •         Surgical instrumentation
  •         Articulating implants, including hips, knees, and shoulders
  •         Dental abutments
