DiaMed: Biocompatible Diamond-Like Coating for Medical Applications

There are various thin diamond-like coatings on the market today, each holding distinct purposes for various applications. With many thin films sharing similar characteristics, finding the right engineering solution for your business can be challenging.

Learn more about DiaMed® thin film and find out what sets it apart from other DLC coatings available to you!

1. DiaMed® is Created from Nano-Crystalline Diamond

With a deep black color, DiaMed® is an amorphous matrix created from layers of nano-crystalline diamond. The unique combination of these elements provides Industrial Hard Carbon with the properties that set it apart from other DLC coatings on the market.

As DiaMed® conforms to substrates, it deposits evenly over all surfaces of a part or product.

2. Its Qualities can Only be Surpassed by Pure Diamond

DiaMed® is characterized by extreme hardness and high wear resistance, corrosion resistance, and lubricity. Its hardness is less than or equal to >8.1 HM > and operates from -200°Celsius to less than 350° Celsius.  DiaMed™ significantly reduces wear resistance, protects the underlying substrate from most corrosive agents, and can withstand less than 46,000 psi tensile and compressive stresses and strain of 0.17 percent.

Furthermore,  the thermal conductivity of DiaMed® is less than 10 W/cm°K, and its electrical resistivity is less than 109-ohm cm, doping options to lower r. This DLC coating prompted a significant reduction in the coefficient of friction during laboratory tests and required torque in field applications compared to bare metal.

The qualities of DiaMed® can only be surpassed by pure diamond – because of this, our DLC coatings succeed where other thin-film coatings fail.

Better for Sterilization

Our coating during testing showed to:

  • Endure the extreme temperature from multiple autoclaves
  • Fill pits and thicken ridges
  • Decrease cell adhesion and activation
  • Reduce platelet adherence and activation
  • Inhibit the significant growth of SY5Y neurofibroblasts


Tribology & Lubrication Technology

The coatings minimization of stiction friction is very important in order to reduce the potential damage to soft body tissue.

Maxillofacial Surgeon

The thin black matte film reduced glare and my resultant eye fatigue under magnification and high-intensity lighting.

I normally sharpen non-thin film instruments annually. These thin film instruments seem to be on the 2–5 year resharpening pace.


Chemical coatings have consistently reduced risks and increased patient safety and comfort.
