  • Publication number: 20220362024
    Abstract: There are provided herein methods and products resulting therefrom. The methods include attaching a pre-fabricated porous ingrowth structure to a substrate by applying heat, or creating and bonding an in-situ-formed porous ingrowth structure from beads on a substrate by applying heat. In some embodiments, an oxidized metal surface of the substrate is diffusion hardened during the heating process. In some embodiments, a vacuum is applied during the heating process. In some embodiments, pressure is applied during the heating process. Also provided herein are assemblies for compressing the pre-fabricated porous ingrowth structure or the beads onto the substrate during the heating process.

  • Publication number: 20190337055
    Abstract: The present disclosure provides methods to improve the properties of a porous structure formed by a rapid manufacturing technique. Embodiments of the present disclosure increase the bonding between the micro-particles 5 on the surface of the porous structure and the porous structure itself without substantially reduce the surface area of the micro-particles. In one aspect, embodiments of the present disclosure improves the bonding while preserving or increasing the friction of the structure against adjacent materials.
