Abstract: A coating for an orbital implant where the coating has an anterior portion having a different, longer term bioabsorbability than a posterior portion. This allows the implant to have a smooth surface for insertion and to provide reduced irritation to neighboring tissues, to help prevent exposure of the porous core of the implant, and to provide a stable anchorment for extraocular muscles, but which also encourages rapid fibrovascular ingrowth. The coating is marked with a visual indicator to facilitate proper orientation. Shell materials are further selected to allow for sterile packaging, the securing of therapeutic agents thereon, and to provide adequately strong securing of the coating to the core. Apertures are formed through the coating to enhance fluid flow to and from the core, and to provide exposure of the surface of the core to extraocular muscles, and for sutures. The apertures are sized and shaped to reduce irritating surface contact with orbital tissues.

Abstract: A surface of an article is heated and subjected to pressure by operation of a friction stir tool. The pressure of the face of the tool on the article surface, and the speed of rotation of the tool and of its progression along the surface of the article, are controlled to progressively hot-work a specified surface area. The face of the tool may be round and have a profiled, axially extending, smaller diameter pin for higher concentration of frictional heat and load and for plasticizing a surface layer of the workpiece. Such hot work may be applied for reducing surface porosity or for producing another change in the surface microstructure, or for effecting another change in surface material properties.
