Morgan Technical Ceramics (MTC) announced
that it produces a range of superior Diamonex® diamond-like carbon (DLC)
biocompatible coatings that are ideal for medical implants, including left
ventricular assist device (LVAD) heart pumps and artificial joints. With
excellent adhesion and wear resistance, Diamonex coatings have significantly
extended component life.The Diamonex 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 start up and
during operation. The coatings provide excellent adhesion
and wear resistant protection for both artificial hip and knee replacements.
The Diamonex 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
feature 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 2-5 microns, eliminating
the need for subsequent machining to achieve fine tolerances.
“The Diamonex optimized DLC coatings are
finely tuned for medical applications,” said Neil Winterbottom, general manager
of MTC Diamonex. “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.”
