摘要:
The present invention relates to methods of treating metal surfaces to enhance adhesion or binding to substrates, and devices formed thereby. In some embodiments of the present invention, methods of achieving improved bonding strength without roughening the topography of a metal surface are provided. The metal surface obtained by this method provides strong bonding to resin layers. The bonding interface between the treated metal and the resin layer exhibits resistance to heat, moisture, and chemicals involved in post-lamination process steps, and therefore can suitably be used in the production of PCB's. Methods according to some embodiments of the present invention are especially useful in the fabrication of high density multilayer PCB's, in particular for PCB's having circuits with line/spacing of equal to and less than 10 microns. Methods according to other embodiments of the present invention are particularly useful in the coating of metal surfaces in a wide variety of applications.

The invention comprises a process comprising infiltrating or infiltrating and coating a substrate with a boron-comprising precursor, and contacting the boron-comprising precursor with a nitrogen-comprising reactant to convert the boron-comprising precursor to BN or other a boron-nitrogen reaction product in the surface porosity or in the surface porosity and on the surface of the substrate. Composite materials comprising as one phase a substrate and BN or other a boron-nitrogen reaction product as a further phase, in surface porosity or in surface porosity and on a surface of the substrate, are claimed.

The present invention provides a blackening treatment method for a black Cr—Co alloy plating film, the method comprising bringing a black Cr—Co alloy plating film having a Cr content of 1 to 15 wt. % into contact with a blackening treatment solution comprising an aqueous solution with a pH value of −1 to 5. According to the present invention, the blackish color of a less blackish plating film formed from a plating bath containing trivalent chromium is enhanced to further improve decorativeness. Furthermore, the corrosion resistance of the film can be more improved by performing electrolytic chromate treatment after blackening treatment.

The invention provides a steel material with satisfactory hydrogen embrittlement resistance, and particularly it relates to high-strength steel with satisfactory hydrogen embrittlement resistance and a strength of 1200 MPa or greater, as well as a process for production thereof. At least one simple or compound deposit of oxides, carbides or nitrides as hydrogen trap sites which trap hydrogen with a specific trap energy is added to steel, where the mean sizes, number densities, and length-to-thickness ratios (aspect ratio) are in specific ranges. By applying the specific steel components and production process it is possible to obtain high-strength steel with excellent hydrogen embrittlement resistance.

The present invention provides technology for rare metal plating of titanium surfaces. A process such as the following would be carried out when manufacturing a partially gold-plated separator for a fuel cell, for example. First, a titanium component made of titanium or titanium alloy is prepared for use as the fuel cell separator (S10). This titanium component is a titanium component whose surfaces are coated with carbon-containing substance. This titanium component is then subjected to a first heat treatment at a prescribed first temperature of between 300 and 700 degrees Celsius (S20). Gold plating of the surfaces of the heat-treated titanium component is then carried out (S80). In this way it is possible to more easily carry out gold electrolytic plating of titanium surfaces.

The present invention is directed to a method for coating a surface of a medical device with a coating composition. The method involves chilling the surface to be coated to below the freezing point of at least one solvent contained in the composition. This coating composition is applied to the chilled surface, and a portion of the coating composition is allowed to freeze onto the surface. The surface can then be heated (either by the application of heat from an external source, by allowing to heat by ambient air) to above the freezing point of the solvent in the coating composition to allow the solvent to thaw and be removed, thereby forming a smooth, uniform coating on the surface of the medical device.

The present invention relates to a magnesium titanate oxide film implant for insertion into a living body, utilized in medical fields such as dentistry, orthopedic surgery, maxillofacial surgery and plastic surgery, and a method for preparing the same. The magnesium titanate oxide film implant in accordance with the present invention is prepared by forming a titanium oxide film (a magnesium titanate oxide film) in which magnesium is incorporated into the surface of titanium or a titanium alloy. A process for preparing a magnesium titanate oxide film implant in accordance with the present invention comprises irradiating UV light on an implant body made of titanium or a titanium alloy in distilled water for more than 2 hours; dipping the UV light-irradiated implant body in an electrolyte solution containing magnesium; and coating a magnesium titanate oxide film on the dipped implant body by anodic oxidation at a voltage of 60 to 500 V. Therefore, the present invention can provide an implant having increased bioactivity of a titanium oxide film formed by anodic oxidation, and provides an optimum magnesium titanate oxide (TixMgyOz) thickness for successful osseointegration of the magnesium titanate (Tix,MgyOz) implant.
