Components operating in the human body
experience high levels of load and experience potentially high wear
situations. In order to withstand this environment biomedical
components require coatings with exceptional hardness, low friction
Amorphous diamond coatings exhibit these
properties and additionally prevent the leaching of metallic ions
into the body.
The characteristics of Adm
amorphous diamond coatings notably their exceptional hardness combined
with their excellent adherence to titanium based alloys and high
grade stainless steel make them ideal candidates for use in medical
The potential applications for the
material include; ball joints, knee joints, hip joints, artificial
heart valves, blood pumps stents and dies for contact lenses.
