  • Publication number: 20220228258
    Abstract: An orthopedic implant having a subsurface level ceramic layer generally includes a base material, an intermix layer molecularly integrated with the base material that includes a mixture of the base material and a plurality of subsurface level ceramic-based molecules implanted into the base material, and an integrated ceramic surface layer molecularly integrated with and extending from the intermix layer forming at least part of a molecular structure of an outer surface of the orthopedic implant. The integrated ceramic surface layer and the base material thereafter cooperate to sandwich the intermix layer in between.

  • Publication number: 20220228259
    Abstract: The process for producing an orthopedic implant having an integrated ceramic surface layer includes steps for positioning the orthopedic implant inside a vacuum chamber, emitting a relatively high energy beam into the at least two different vaporized metalloid or transition metal atoms in the vacuum chamber to cause a collision therein to form ceramic molecules, and driving the ceramic molecules with the ion beam into an outer surface of the orthopedic implant at a relatively high energy such that the ceramic molecules implant therein and form at least a part of the molecular structure of the outer surface of the orthopedic implant, thereby forming the integrated ceramic surface layer.

  • Patent number: 10619238
    Abstract: The process for producing an orthopedic implant having an integrated silicon nitride surface layer includes steps for positioning the orthopedic implant inside a vacuum chamber, mixing nitrogen gas and vaporized silicon atoms in the vacuum chamber, emitting a relatively high energy beam into the mixture of nitrogen gas and vaporized silicon atoms in the vacuum chamber to cause a gas-phase reaction between the nitrogen gas and the vaporized silicon atoms to form reacted precipitate silicon nitride molecules, and driving the precipitate silicon nitride molecules with the same beam into an outer surface of the orthopedic implant at a relatively high energy such that the precipitate silicon nitride molecules implant therein and form at least a part of the molecular structure of the outer surface of the orthopedic implant, thereby forming the integrated silicon nitride surface layer.
