Science and technology of multifunctional/low cost ultranano- crystalline diamond (UNCDTM) coatings and applications to new generation of external and implantable medical devices

UNCD films, developed/patented by Auciello and colleagues, are grown on many substrates by novel MPCVD and HFCVD technique, using Ar/CH4 chemistry, producing films with 2-5 nm grains. The UNCD films exhibit the lowest friction coefficient (0.02-0.04) compared with metals (≥ 0.5) currently used in many prostheses (e.g., hips, knees), electrically conductive Nitrogen-doped N-UNCD coatings enable a new generation of corrosion resistant electrodes, UNCD coatings are the best biocompatible material, made of C atoms (element of life in the human DNA, cells, and molecules). OBI-USA/OBI-México are developing new generations of external and implantable medical devices based on UNCD coatings, namely: a)
