摘要:
A method for forming a connection such as an electrical connection, to a fibre material electrode element comprises moving a length of the fibre material relative to a pressure injection stage and pressure impregnating by a series of pressure injection pulses a lug material into a lug zone part of the fibre material to surround and/or penetrate fibres of the fibre material and form a lug strip in the lug zone. The fibre material may be a carbon fibre material and the lug material a metal such as Pb or a Pb alloy. Apparatus for forming an electrical connection to a fibre material electrode element is also disclosed.

Provided is a titanium cast product made of commercially pure titanium, the titanium cast product being produced by electron-beam remelting or plasma arc melting, comprising: a melted and resolidified layer in a range of 1 mm or more in depth at a surface serving as a surface to be rolled, the melted and resolidified layer being obtained by adding one or more kinds of β stabilizer elements to the surface and melting and resolidifying the surface. An average value of β stabilizer element(s) concentration in a range of within 1 mm in depth is higher than β stabilizer element(s) concentration in a base material by, in mass %, equal to or more than 0.08 mass % and equal to or less than 1.50 mass %. As the material containing the β stabilizer element, powder, a chip, wire, or foil is used. As means for melting a surface layer, electron-beam heating and plasma arc heating are used.

A method of fabricating a liquid for an oxide thin film is provided, which includes mixing at least two kinds of dispersoids selected from the group consisting of a Zinc compound, an Indium compound, a Gallium compound, a Tin compound and a Thallium compound, with dispersion media corresponding to the selected dispersoids to form a dispersion system, and stirring and aging the dispersion system at a predetermined temperature for a predetermined time, wherein a molar ratio of the Zinc compound to each of the Indium compound, Gallium compound, Tin compound and Thallium compound is 1:0.1 to 1:2. According to the present invention, the liquid for the oxide thin film may be fabricated by a sol-gel method making it capable of being implemented in mass production in a simple and low-cost manner as opposed to the conventional vacuum deposition method.

A large strain polymer nanocomposite actuator is provided that upon subjected to an external stimulus, such as a magnetic field (static or electromagnetic field), an electric field, thermal energy, light, etc., will deform to thereby enable mechanical manipulations of structural components in a remote and wireless manner.
摘要:
The loss of aluminum content during the laser (20) deposition of superalloy powders (16) is accommodated by melting pure aluminum foil (14) with the superalloy powder to increase a concentration of aluminum in the melt pool (24) so that the resulting layer of deposited material (26) has a desired elemental composition Foils, screens or strips of any material may be melted with powders to achieve any desired cladding composition, including a graded composition across a thickness of a clad layer (50).
摘要:
A metal filling apparatus fills molten metal into a minute space formed on a surface of a semiconductor wafer. The apparatus has a processor body with a chamber in which the wafer is held, a molten metal supply, and a molten metal recovery mechanism. The supply includes a tank in which molten metal is stored, a supply pipe connected between the chamber and the tank, a supplier interposed in the supply pipe to supply molten metal from the tank to the processing chamber, and the recovery mechanism recovers molten metal from the processing chamber.
摘要:
A method for manufacturing a metal-ceramic composite structure for high temperature exposure is provided, whereby the composite structure includes a base metal structure or component, which is on at least one side covered and permanently joined with one or more ceramic tiles. The method may include the steps of: manufacturing green bodies with cavities and sintering the green bodies to receive ceramic tiles into cavities; arranging the ceramic tiles in a cast mould; pouring liquid metal into the cast mould to substantially fill the cavities; creating an intermediate metal layer; and solidifying the liquid metal to permanently join the ceramic tiles and the intermediate metal layer.
摘要:
A method of bonding a metal to a substrate is disclosed herein. The method involves forming a nano-brush on a surface of the substrate, where the nano-brush includes a plurality of nano-wires extending above the substrate surface. In a molten state, the metal is introduced onto the substrate surface, and the metal surrounds the nano-wires. Upon cooling, the metal surrounding the nano-wires solidifies, and during the solidifying, at least a mechanical interlock is formed between the metal and the substrate.
摘要:
This invention discloses a metal coating method whereby an abrasion resistant and wear resistant coating is first applied to the that portion of a metal object of extended size to be protected, the coating is then fused onto the metal object with the use of a temperature controlled induction heater, which results in a metal object, at least a portion of which is more abrasion resistant and wear resistant than the uncoated metal object.
摘要:
