    Abstract: A method of inhibiting corrosion of duplex stainless steel by aqueous acidic solution, comprises carrying out a preliminary treatment which is passivation of the steel while exposing the steel to a first aqueous acidic solution containing at least one organic corrosion inhibitor able to adsorb to a steel surface, so as to deposit a passivating and corrosion inhibiting film on the steel surface; and thereafter during a second period of time exposing the steel to a second aqueous acidic solution different from the first aqueous acidic solution and also containing at least one organic corrosion inhibitor able to adsorb to a steel. The second aqueous acidic solution maintains the film on the steel surface, such that weight loss through corrosion in the second period of time is lower than the weight loss which would be observed with the same second aqueous acidic solution but without carrying out the preliminary treatment.

  • Patent number: 9759861
    Abstract: A sequence of processing steps presented herein is used to embed an optical signal path within an array of nanowires, using only one lithography step. Using the techniques disclosed, it is not necessary to mask electrical features while forming optical features, and vice versa. Instead, optical and electrical signal paths can be created substantially simultaneously in the same masking cycle. This is made possible by a disparity in the widths of the respective features, the optical signal paths being significantly wider than the electrical ones. Using a damascene process, the structures of disparate widths are plated with metal that over-fills narrow trenches and under-fills a wide trench. An optical cladding material can then be deposited into the trench so as to surround an optical core for light transmission.

  • Patent number: 8652317
    Abstract: An alumina nanohole array and a method of fabricating the same includes the steps of forming an aluminum thin-film on a substrate at a substrate temperature of ?80° C. or below so that crystal grain growth is suppressed, even when a high-purity aluminum material is used, thus providing improved surface smoothness; and anodizing the aluminum thin-film. Preferably, the method additionally includes texturing by pressing a mold having an orderly array of projections against the aluminum thin-film to form pits on the aluminum thin-film which enables a larger array area to be formed. When the mold and the aluminum thin-film are held at a temperature of 150 to 200° C., the pressure used for pit formation is reduced. A magnetic recording medium manufactured by a method therefore includes forming a magnetic layer within the nanoholes so that the medium is suitable as a bit patterned media for a perpendicular recording system.

    Abstract: There is provided a metallic glass component with its surface layer having both durability of a film and chromatic color properties, and a method for forming the surface layer. Surface active treatment is performed wherein the surface of the metallic glass component is reacted with a mixed aqueous solution of nitric acid and hydrofluoric acid to remove an oxide film and to provide an anchor bond shape on the surface of a metallic glass component, and electroplating or electroless plating is then performed, to form a plating film on the surface of the metallic glass component. It is thereby possible to form a surface layer of a metallic glass which has both durability and a chromatic color.

  • Patent number: 7641782
    Abstract: A method and apparatus for improving the corrosion resistance of chrome plated materials. After the materials to be chrome plated are mechanically abrasively polished, but before they are reverse etched, they are power washed with a high-pressure liquid. A sprayer with nozzles directed inwardly towards the materials directs water onto the material at pressures in the range of 1000 or 2500 to 3000 psi. After the materials are chrome plated, they are heated above the melting point of a buffing compound, and then the heated materials with the buffing compound applied are buffed. An induction heater is used, before or after the buffing compound is applied. Computer controls, responsive to operator input of the cross-sectional size, composition and/or speed of movement of the chrome plated materials, to in turn regulate the power to an induction coil heater.

  • Patent number: 7550070
    Abstract: An electrode assembly includes a distribution plate having a plurality of grooves that communicate with openings in an overlying polishing pad layer. The grooves include end openings that allow for draining of process solution, both during processing and subsequent cleaning/rinsing of the pad. Drainage occurs continually during processing, cleaning and rinsing, and so is constricted through the end openings relative to the grooves, to prevent wastage. The end openings are sufficiently large, however, to substantially completely drain fluids from the grooves between steps without delaying robotic motions.

  • Publication number: 20090145769
    Abstract: An alumina nanohole array and a method of fabricating the same includes the steps of forming an aluminum thin-film on a substrate at a substrate temperature of ?80° C. or below so that crystal grain growth is suppressed, even when a high-purity aluminum material is used, thus providing improved surface smoothness; and anodizing the aluminum thin-film. Preferably, the method additionally includes texturing by pressing a mold having an orderly array of projections against the aluminum thin-film to form pits on the aluminum thin-film which enables a larger array area to be formed. When the mold and the aluminum thin-film are held at a temperature of 150 to 200° C., the pressure used for pit formation is reduced. A magnetic recording medium manufactured by a method therefore includes forming a magnetic layer within the nanoholes so that the medium is suitable as a bit patterned media for a perpendicular recording system.

  • Patent number: 7517444
    Abstract: The present invention relates to methods and apparatus for plating a conductive material on a workpiece surface in a highly desirable manner. Using a workpiece-surface-influencing device, such as a mask or sweeper, that preferentially contacts the top surface of the workpiece, relative movement between the workpiece and the workpiece-surface-influencing device is established so that an additive in the electrolyte solution disposed on the workpiece and which is adsorbed onto the top surface is removed or otherwise its amount or concentration changed with respect to the additive on the cavity surface of the workpiece. Plating of the conductive material can place prior to, during and after usage of the workpiece-surface-influencing device, particularly after the workpiece surface influencing device no longer contacts any portion of the top surface of the workpiece, to achieve desirable semiconductor structures.

  • Patent number: 7361261
    Abstract: A solid substrate comprising a surface comprising an achiral array of atoms having thereupon a chiral metal oxide surface. The chiral metal oxide surface is prepared by electrodeposition of a chiral metal oxide array from a solution of a chiral salt of the metal. In one embodiment, chiral CuO is grown on achiral Au(001) by epitaxial electrodeposition. The handedness of the film is determined by the specific enantiomer of tartrate ion in the deposition solution. (R,R)-tartrate produces an S—CuO(1 1 1) film, while (S,S)-tartrate produces an R—CuO( 11 1) film. These chiral CuO films are enantiospecific for the electrochemical oxidation of(R,R) and (S,S)-tartrate.
