Diamonex Biocompatible Coatings From Morgan Technical Ceramics

Suited for such medical implantable applications as left-ventricular-assist-device (LVAD) heart pumps and artificial joints, the new range of diamond-like-carbon (DLC) biocompatible coatings exhibit good adhesion and wear resistance. The precision coatings of the Diamonex range provide a superhard, low-friction surface with properties approaching those of natural diamond. The low coefficient of friction, ranging between 0.03 and 0.25, increases device mechanical efficiency at startup and during operation as well. In addition, the DLC coatings feature a high hardness of 15 to 30 GPa, which prevents fretting and galling while enhancing durability. They can be applied to both flat surfaces and 3-D parts via direct-ion-beam or radio-frequency plasma-enhanced chemical vapor deposition techniques. Smooth and highly conformal, the coatings typically are applied in a thickness ranging from 2-5 µm.
