  • Carbon coatings, method and apparatus for applying them, and articles bearing such coatings
    Patent number: 6726993
    Abstract: Articles are disclosed which bear a carbon coating layer, wherein carbon-carbon bonding within the coating layer is mostly of the sp2 form: wherein the coating has a specific wear rate under wet conditions of less than 10−6 m3/Nm: wherein the coating has an adhesion critical load of at least 70N: wherein the coating has a hardness of at least 1000 VHN: wherein the coating has a coefficient of friction (dry) of not more than 01. The coating may be a multi-layer coating containing successive metal-containing and carbon layers. The article may be constituted as a medical prosthesis. Methods are disclosed of forming hard wear resistant carbon coatings by sputter ion plating with at least one carbon target in which an ion current density of for example above 0.
