N2 Biomedical’s proprietary IonGuard® ion implantation process utilizes direct ion beam bombardment to create a hard, low friction, and hydrophilic surface without adding a coating layer to the surface or changing the bulk properties of the device. This low temperature process has been used to treat millions of medical device implants including metal knees and hips and orthodontic arch wires.

Ion implantation is a highly controllable process for modifying physical and chemical surface properties of materials. Many surface properties can be improved with ion implantation including hardness, wear resistance, resistance to chemical attack, and reduced friction. The process can be applied to virtually any material, including most metals, ceramics and polymers.

The process is extremely controllable and reproducible and can be tailored to modify different surfaces in desired ways.
