[ LAST LONGER ]

N2 Biomedical’s proprietary Ion Implantation Surface Treatment and IBAD Nano-Engineered Coating technologies reduce wear and fretting, and improve the corrosion resistance of metallic substrates. N2 Biomedical’s surface treatments have been used on millions of medical device implants over the past 30 years.

Reduced Wear and Fretting with IonGuard

N2 Biomedical’s proprietary IonGuard® process utilizes direct ion beam bombardment to create a hard, low friction, and hydrophilic surface without 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.

IonGuard® treated Titanium knees show wear properties comparable to Co-Cr devices in a 3 million cycle wear study. IonGuard® treated Titanium hip components release 35 times less metal than untreated parts after 1 million wear cycles.

IonGuard®  treated Co-Cr heads remain up to 29% smoother than untreated heads in clinical usage. Multiple clinical studies with multi-year follow-up have demonstrated up to a 40% reduction in wear rates for mating polyethylene surfaces. IonGuard®  treated Co-Cr heads have shown superior performance in a 5 million cycle wear simulation test as compared to TiN-coated Co-Cr and  comparable wear to ceramic-based heads.

Increased Lubricity

N2 Biomedical’s proprietary IonGuard® surface treatments and IBAD NanoCoatings can be engineered to reduce surface friction and improve hydrophillicity on a variety of polymer, metal and ceramic substrates. Our highly adherent coatings reduce the surface friction and tackiness without changing the bulk properties of the device.
