Abstract: A coated titanium material includes a titanium material and a coating film formed on a surface of the titanium material. A Ti-based oxide is included in an interface between the titanium material and the coating film. The Ti-based oxide is one or both rutile type TiO2 and Ti2O3. In a case where a cut surface of the coating film is formed by using a SAICAS method under conditions that a horizontal speed is 2 μm/s and a vertical speed is 0.1 μm/s, on the cut surface, an area percentage of the Ti-based oxide is 30.0% or more in a region having a distance of 15 μm from a reference line specified on the basis of a boundary line, which is an intersection line between the cut surface and the interface, to a coating film side.

Abstract: The present disclosure provides a preparation method of a titanium implant with a surface coating in a crater-like porous shape. A titanium substrate is subjected to polishing, cleaning, and first drying in sequence to obtain a pretreated titanium substrate. This step eliminates an influence of roughness and surface impurities of the titanium substrate on roughness and a structure of a coating formed on a surface of the titanium substrate after micro-arc oxidation, so as to obtain a titanium implant with a specific structure and a desirable biological performance. The micro-arc oxidation is conducted using the pretreated titanium substrate as an anode and iron as a cathode in an electrolyte containing sodium phosphate. In this step, a micro-arc oxidation coating is formed on the surface of the titanium substrate to obtain the titanium implant with a surface coating in a crater-like porous shape.

Abstract: A method of patterning a layer of superconductor material comprises: forming a mask over the layer of superconductor material, the mask having at least one opening; depositing a layer of anodizable metal in the at least one opening, over a portion of the layer of superconductor material; removing the mask; and performing anodic oxidation, whereby the layer of anodizable metal protects the portion of the layer of the superconductor material from the anodic oxidation. The superconductor material is aluminium. The method allows for patterning of the superconductor material without the use of a chemical etch. This may in turn allow for improvements in resolution, and/or may avoid damage to further components or interfaces between components which may be present during the patterning. Also provided are the use of a titanium layer to protect an aluminium layer from anodic oxidation, and a semiconductor-superconductor hybrid device obtainable by the method.

Abstract: Embodiments of nanostructures comprising metal oxide and methods for forming the nanostructure on surfaces are disclosed. In certain embodiments, the nanostructures can be formed on a substrate made of a nickel titanium alloy, resulting in a nanostructure containing both titanium oxide and nickel oxide. The nanostructure can include a lattice layer disposed on top of a nanotube layer. The distal surface of the lattice layer can have a titanium oxide to nickel oxide ratio of greater than 10:1, or about 17:1, resulting in a nanostructure that promotes human endothelial cell migration and proliferation at the interface between the lattice layer and human cells or tissue. The nanostructure may be formed on the outer surface of an implantable medical device, such a stent or an orthopedic implant (e.g. knee implant, bone screw, or bone staple).

Abstract: Metal components that require anodic coating or anodizing, may also require some surfaces of the component to be free of the anodic coating for the purpose of conductivity. The presence of the anodic coating on surfaces of the component that require conductivity would make those surface more electrically resistant or nonconductive. A combination of a gas pocket or air bubble to create a barrier to anodizing in a cavities of a workpiece (or in a cavity created by a conformal compression material) and the use of a (e.g., compressible) mask/seal material to mask off other surfaces though a gasket sealing function, is used. The mask/seal material may be compressed and makes a seal of some surfaces using pressure from clamping or pressure mechanisms. At least two opposing surfaces are masked by the compressive mask/seal material on one end and a gas pocket on the other end. The gas pocket will allow the anode to make firm electrical contact with the workpiece. The unmasked surfaces of the workpiece will be contacted by the electrolyte and consequently anodized. These anodized surfaces will have more electrical resistance (e.g., have higher resistance, and might even be non-conductive) than the masked surfaces that were not anodized. Further, the selectively anodized surfaces can be colored, seal, or have other conventional post anodizing processes applied.
