Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant.

An object of the present invention is to provide a method for producing a metal laminate material that maintains sufficient bonding strength and has superior production efficiency. A method for producing a metal laminate material by bonding two sheets, one sheet composed of a material M1 and the other sheet composed of a material M2, wherein each of M1 and M2 is a metal or alloy comprising any one or more selected from the group consisting of Mg, Al, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Nb, Mo, Pd, Ag, In, Sn, Hf, Ta, W, Pb, and Bi, comprises the steps of subjecting the faces of the two sheets to be bonded to sputtering treatment with inert gas ions under vacuum such that oxide layers on surface layers remain; temporarily bonding the two sheets by roll pressure bonding; and conducting a thermal treatment to thereby bond the two sheets, and, when Tm1>Tm2 where Tm1 (K) is the melting point of M1 and Tm2(K) is the melting point of M2, the temperature of the thermal treatment is 0.45Tm2 or more and less than 0.45Tm1, provided that the temperature is not more than Tm2.

A method for joining a ceramic component to a metallic component is described. At least one initial layer of an active metal is applied to one of the joining surfaces, by a cold spray technique. At least one second layer of a nickel-based braze composition is then applied over the initial layer by cold-spraying. The braze composition and components are then heated, so as to form an active braze joint between them. A method of sealing an open region of a sodium metal halide-based battery is also disclosed, using the brazing technique described herein to form braze joints that seal various components in the battery cells, such as metallic rings and ceramic collar structures.

Methods, processes, systems, devices and apparatus are provided for additive manufacture resulting in the 3D printing of novel ceramic composites. Additive manufacture or 3D printing of bulk ceramic and ceramic composite components occurs at considerably lower temperatures and shorter manufacturing intervals than the current state of the art. The methods, processes, systems, devices and apparatus and selection of precursor resins produce ceramic and ceramic composite material systems which have not been produced before by 3D printing.

The present disclosure is directed to a multi-segment device comprising an elongate first portion comprising a first metallic material, an elongate second portion comprising a different metallic material, the first and second elongate portions being directly joined together end to end, a heat affected zone surrounding an interface of the elongate first portion and the elongate second portion, a shapeable distal end formed from at least a portion of the elongate second portion, a coil disposed about a portion of the elongate second portion.

A sliding member includes a substrate containing Fe as a main component and an alloy layer overlaid on the substrate and composed of a Cu-base alloy containing 6 to 12% by mass of Ni and 3 to 9% by mass of Sn. The alloy layer has a body layer and an intermediate layer. The body layer is formed of the Cu-base alloy, while the intermediate layer is composed of an alloy containing Ni, Sn, and Cu which are derived from the Cu-base alloy and Fe derived from the substrate. Taking side close to the substrate as a lower region and the other side as an upper region, a ratio of the total area of hard phases to the observation section of the upper region is 1.2 to 3.0, where the ratio of the total area of the hard phases to the observation section of the lower region is set at 1.

A system for non-destructive defect detection includes a calibration block and at least two phased array probes configured to transmit and receive pulsed echo signals. The calibration block includes a base metal having a first surface opposite a second surface, a corrosion resistant alloy coupled to the first surface of the calibration block, and a manual weld overlay extending from the first surface of the calibration block to a second surface of the calibration block. A method for non-destructive defect detection includes providing a system for non-destructive defect detection and calibrating at least two phased array probes of the system for non-destructive defect detection to form at least two calibrated phased array probes.

A mask assembly includes: a mask frame provided with a first opening defined through a center portion thereof and including an outer frame surrounding the first opening and provided with at least one concave portion defined therein; a mask body disposed to correspond to the first opening and provided with second openings defined therethrough and having an area smaller than the first opening; a first sub-mask disposed on the mask body, provided with third openings defined therethrough over an entire area thereof and having an area smaller than each of the second openings, and including a metal material; a second sub-mask disposed on the first sub-mask, provided with fourth openings defined therethrough over an entire area thereof and having an area smaller than each of the third openings in a plane, and including a polymer material; and a welding portion disposed on the second sub-mask in the concave portion.

The present disclosure is directed to a multi-segment device comprising an elongate first portion comprising a first metallic material, an elongate second portion comprising a different metallic material, the first and second elongate portions being directly joined together end to end, a heat affected zone surrounding an interface of the elongate first portion and the elongate second portion, a shapeable distal end formed from at least a portion of the elongate second portion, a coil disposed about a portion of the elongate second portion.
