Morgan: Biocompatible Carbon Coatings
Longer lifetime coatings for medical parts.
Stourport, Worcestershire, UK — Morgan Technical Ceramics (MTC) is now producing a range of superior Diamonex® diamond-like carbon (DLC) biocompatible coatings that are especially suitable for medical implants, including left ventricular assist device (LVAD) heart pumps and artificial joints. With excellent adhesion and wear resistance, the Diamonex coatings have significantly extended component life.

The company's range of optimized DLC coatings provide a super-hard, low friction coating with properties approaching those of natural diamond. Applied to both LVAD housing and rotor elements, the coatings provide a medical barrier and wear-resistant coating that lengthens the life of the device. In addition, the low coefficient-of-friction (0.03-0.25) also increases the mechanical efficiency by minimizing friction at startup and during operation. The coatings provide excellent adhesion and wear-resistant protection for both artificial hip and knee replacements.

The DLC coatings can be applied to both flat surfaces and 3-dimensional parts, using either direct ion beam or radio frequency plasma-enhanced chemical vapor deposition techniques. They provide a high hardness of 15-30 gigapascals (GPa), which extends lifetime and prevents fretting and galling. The DLC coatings are also smooth and highly conformal, with typical coating thicknesses of just 2 to 5µ, eliminating the need for subsequent machining to achieve fine tolerances.

According to the company, the Diamonex optimized DLC coatings are finely tuned for medical applications. Customers using the medical DLC coatings are seeing significant improvements in LVAD heart pump devices, knee implants, and other artificial joints when compared to other available coatings.
