Medthin™ 60 - Implants
The high oxidation resistance coating
Medthin™ 60 coating is particularly suitable for improving articulating joints such as those of “Coating on UHMWPE” where polyethylene wear and ion release from substrates (CoCr, SS, TAV, etc) is strongly reduced. The coating is applied with thickness of about 5 µm and it has adhesion strength to metal substrates in the GigaPascal range. The ZrN layer improves UHMWPE abrasion resistance >65% measured on knee simulator tests compliant with ISO 14243. Zirconium Nitride (ZrN) is deposited with latest generation technologies showing a polycrystalline cubic structure with a fine and very dense structure, roughness (Ra) values below 0.05µm, ideal for articulating zones. The coating coverage is rather uniform on external surfaces while internal surfaces are difficult to coat.
Ionbond can currently deliver coating service of “Medthin™ 60 ZrN on Implants” from multiple coating centers.
