More Safe

Reduced Allergy Potential

A significant reduction in the release of metal ions is obtained when the implant surface is coated with TiNbN. Coating with TiNbN prevents direct contact of the base material with the surrounding tissue and reduces the release of particles and ions due to wear and corrosion.


Coated and uncoated test specimens were investigated to demonstrate the release of cobalt, chromium and nickel ions in body fluids.

Potential To Be More Durable


Reduced Wetting Angle

The wetting angle of the implant surfaces coated with TiNbN is reduced by 20° when compared with uncoated implant surfaces thus resulting in greater hydrophilicity of the implant surface for body fluids. Smaller the contact angle, better the wettability and improved lubrication which helps to reduce the wear by decreasing the friction between the articulating surfaces.

Increased Wear Resistance

As a result of the hardness of the TiNbN coating and the ceramic-like properties in terms of adhesion behavior and the wetting angle with liquids, the TiNbN coating shows an outstanding frictional coecient in contact with UHMWPE.


Almost 40% reduction in wear of UHMWPE is observed in a “Pin on disc” test when investigated with 1 million cycles between the uncoated and TiNbN-coated specimens.
