  • Publication number: 20200165703
    Abstract: Disclosed is a method of producing titanium and titanium alloy nanopowder from titanium-containing slag through a shortened process. The method includes: (1) subjecting titanium-containing slag to high-temperature oxidation and enrichment and then melting to precipitate titanium-enriched slag; (2) subjecting the titanium-enriched slag to pulverization and gravity flotation; (3) carrying out secondary enrichment; (4) preparing a molten salt reaction system; (5) synthesizing titanium and salt-containing titanium alloy nanopowder by reduction reaction; and (6) vacuum filtering, pickling, washing and vacuum drying the salt-containing titanium alloy nanopowder; and then separating titanium alloy nanopowder from the molten salt. Using the present method, the titanium-containing slag can be continuously treated to produce titanium and titanium alloy nanopowder. It requires a shortened process, a simple equipment and low energy consumption.

  • Patent number: 10650850
    Abstract: A hard disk drive has a gas-bearing slider supporting a write head with an electrically conductive structure, like a spin-torque oscillator (STO), in the write gap, and dual independent interface voltage control (IVC) circuitry coupled to elements on the slider. A first IVC circuitry provides a bias voltage to the slider body to assure substantially zero electrical potential between the slider body and the disk to minimize slider-disk contact and lubrication pick-up. A second IVC circuitry operates independently of the first IVC circuitry and provides a bias voltage to the electrically conductive structure region to assure a negative potential of the electrically conductive structure region relative to the disk to minimize degradation of the slider overcoat and thus oxidation of the electrically conductive structure.

  • Patent number: 10596663
    Abstract: The present disclosure relates to a method for high precision laser processing of sapphire with submicron-order section plane using a picosecond-order pulse laser which has high transmittance wavelength to sapphire. The laser triggers ultrafine phase transformation points or electronic state removal points from a lower surface of sapphire. After elevating focal points, a trace which is parallel to laser incident direction is formed. Under a chemical corrosion environment, points of the laser trace are arranged to intersect with other another according to the cutting route to form the corresponding phase transformation region and electronic state removal region. At the same time, by utilizing the catalysis effect of microthermal effect of picosecond laser on chemical corrosion, separation of the sapphire sample along the processing path is obtained.
