Medthin™ 43 ADLC

The high class coating for implants

Medthin 43 coating is excellent to improve articulating joints such as those of “Coating on UHMWPE” where polyethylene wear and ion release from substrates (CoCr, SS, TAV, etc)  is reduced nearly to zero. The coating is applied with thickness of about 3 µm and it has adhesion strength to metal substrates higher than 0.8 GPa. Amorphous Diamond Like Carbon (ADLC) is deposited with latest generation Plasma Assisted Chemical Vapor Deposition Technologies (PACVD) showing an amorphous phase virtually with no pores and roughness (Ra) values below 0.02µm, ideal for articulating zones. The coating coverage is rather uniform on external surfaces whereas for inner surfaces a Ionbond proprietary technology can be applied in some cases.  
Ionbond  can currently deliver coating service of “Medthin 43 ADLC on Implants” from Switzerland, France and UK and the coating properties/characteristics have been filed in a FDA master file (MAF) number 1647. The MAF can be referred upon request and common agreement with Ionbond.
