  • Patent number: 10030312
    Abstract: Power pulsing, such as current pulsing, is used to control the structures of metals and alloys electrodeposited in non-aqueous electrolytes. Using waveforms containing different types of pulses: cathodic, off-time and anodic, internal microstructure, such as grain size, phase composition, phase domain size, phase arrangement or distribution and surface morphologies of the as-deposited alloys can be tailored. Additionally, these alloys exhibit superior macroscopic mechanical properties, such as strength, hardness, ductility and density. Waveform shape methods can produce aluminum alloys that are comparably hard (about 5 GPa and as ductile (about 13% elongation at fracture) as steel yet nearly as light as aluminum; or, stated differently, harder than aluminum alloys, yet lighter than steel, at a similar ductility. Al—Mn alloys have been made with such strength to weight ratios. Additional properties can be controlled, using the shape of the current waveform.

  • Publication number: 20110048955
    Abstract: Aspects of the present disclosure are directed to electrochemical approaches for synthesis of platinum-iridium alloys with selected platinum-iridium ratio content and subsequently predetermined mechanical properties and electrochemical impedance properties. Such can provide a simple and cost-effective process for preparing these electrodes, as compared to conventional thin film processing techniques. A three-electrode electrochemical electrodeposition system is described including an electrochemical cell with a working electrode on which the electrodeposited film is deposited, a counter electrode to complete the electrochemical circuit and a reference electrode to measure and control surface potential. Mixed layers of platinum atoms and iridium atoms can be deposited from electrolyte solution onto the working electrode surface to create an electrically conductive surface with material properties related to the composition of the as-deposited film.

  • Publication number: 20100314255
    Abstract: There is provided a substantially permanent stainless steel cathode plate suitable for use in electrorefining of metal cathodes, the cathode being composed of a low-nickel duplex steel or a lower grade “304” steel, wherein operational adherence of an electrodeposition thereon is enabled by altering various qualities of the cathode surface. There is also provided a method of producing the above duplex or Grade 304 cathode plates, such that the desired operational adherence of the deposit upon the plate is not so strong as to prevent the deposit being removed during subsequent handling.
