  • Patent number: 10799947
    Abstract: The present invention relates to a method of semi-solid indirect squeeze casting for Mg-based composite material, which aims at improving the mechanical property of the cast by adding magnesium zinc yttrium quasicrystal of high hardness, high elastic modulus and excellent matrix binding property acting as the reinforcement into the magnesium alloy matrix and manufacturing the cast through smelting using a vacuum atmosphere smelting furnace, agitating with ultrasonic wave assisted vibration in the rotating impeller jet agitation furnace and indirect squeeze casting against the problem of poor wettability, easy agglomeration, inhomogeneous distribution between the reinforcement particles and the matrix materials and poor properties of the manufactured cast. The manufacturing method of the present invention has advanced technologies and detailed and accurate data.

  • Patent number: 10309000
    Abstract: The present invention relates to a method for preparing an aluminum-copper-iron quasicrystal and silicon carbide mixed reinforced aluminum matrix composite, where the aluminum-copper-iron quasicrystal and silicon carbide mixed reinforced aluminum matrix composite is prepared with an aluminum alloy serving as a matrix and with aluminum-copper-iron quasicrystal and silicon carbide serving as reinforcement agents via smelting in an intermediate-frequency induction melting furnace through the process of intermediate-frequency induction heating, vacuumizing, bottom blowing argon, and casting molding in view of low hardness and low tensile strength of aluminum matrix materials. The prepared aluminum-copper-iron quasicrystal and silicon carbide mixed reinforced aluminum matrix composite has a hardness of 80.3 HB which is improved by 50.64% and tensile strength of 285 Mpa which is improved by 60.42%, and corrosion resistance thereof is improved by 40%.

  • Publication number: 20060213371
    Abstract: A coffee maker includes a base, a lower portion of a body, an upper portion of the body, a heater, and a water pipe. The base is placed at the bottom of the coffee maker and connected to the lower portion of the body through screws. The base has a supporter by which a coffee cup can be supported. The upper portion of the body comprising a water tank, a lid, an infusing house and a flow distributor, is placed on the top of the body. The coffee maker also includes an actuating mechanism, which allows the upper portion of the body to move up or down. Upon the height of the coffee cup placed at the supporter, by turning a knob of the actuating mechanism, the upper portion of the body may be adjusted to prevent coffee from spaying out from the coffee cup.
