  • Publication number: 20230330303
    Abstract: A medical implant is disclosed. The medical implant includes: a first biocompatible metal forming a substrate (210, 310, 410), a second biocompatible metal diffused into the first biocompatible metal to form an biocompatible alloy surface (220, 314, 414), the alloy surface further including a diffusion hardening species, wherein the diffusion hardening species may be carbon, nitrogen, oxygen, boron, or any combination thereof. A method of forming a medical implant is also disclosed. The method includes the steps of: providing a first biocompatible metal or alloy that forms a substrate (210, 310, 410), providing a second biocompatible metal or alloy, diffusing the second biocompatible metal into the first biocompatible metal to form an alloy layer (220, 314, 414), removing excess second metal material from the substrate to expose the alloy layer, and diffusion hardening the alloy layer.

  • Publication number: 20220168106
    Abstract: Medical devices, such as implants, and corresponding methods of manufacturing using an additive manufacturing technique, wherein the finished medical devices include a build plate retained therein, are disclosed. In some embodiments, the medical device includes a build plate having a plurality of peaks and a plurality of indentations, the plurality of peaks and the plurality of indentations together defining a surface roughness of an exterior surface of the build plate. The medical device may further include a first layer formed atop the exterior surface of the build plate, the first layer comprising a plurality of powder structures disposed over the plurality of peaks and the plurality of indentations. In some embodiments, an average peak distance between adjacent peaks of the plurality of peaks is less than an average width dimension of at least a portion of the plurality of powder structures.

  • Patent number: 9764061
    Abstract: A coating of blue-black or black zirconium of uniform and controlled thickness on a zirconium or zirconium alloy material is accomplished through the treatment of an amorphous zirconium or zirconium alloy substrate, which may have an altered surface roughness. The treatment of amorphous zirconium or zirconium alloy substrates includes oxidation of the substrates. A zirconium coating of uniform and controlled thickness is especially useful in various applications because the uniformly thick zirconium surface of controlled depth provide a barrier against implant corrosion caused by ionization of the metal substrates.
