The invention provides a power module substrate with a heat sink, which includes a power module substrate provided with an insulating substrate, a circuit layer provided on one surface of the insulating substrate and a metal layer provided on the other surface of the insulating substrate. The heat sink is bonded to the power module substrate via a bonding layer (30) to a surface on an opposite side to the insulating substrate of the metal layer. Bonding layer is a sintered body of silver particles, a porous body having a relative density in a range of 60% or more and 90% or less, and having a thickness in a range of 10 μm or more and 500 μm or less.

In an example of a method for three-dimensional (3D) printing, build material layers are patterned to form an intermediate structure. During patterning, a binding agent is selectively applied to define a patterned intermediate part. Also during patterning, i) the binding agent and a separate agent including a gas precursor are, or ii) a combined agent including a binder and the gas precursor is, selectively applied to define a build material support structure adjacent to at least a portion of the patterned intermediate part. The intermediate structure is heated to a temperature that activates the gas precursor to create gas pockets in the build material support structure.

A magnetic inductor for heating parts by means of induction having a geometry with a density greater than or equal to 99.9% (absence of pores), produced by a plurality of welded layers formed by metal dust particles of a conductive, non-magnetic material (such as, inter alia, copper, tin, aluminium, gold, or silver), preferably copper or a copper-based alloy, having a spherical shape and a grain size between 40 and 100 μm, and in a single-piece part including electrical and mechanical connections. Also, a method for producing the magnetic inductor with EBM technology (electron beam melting/production technology based on electron beam fusion), using a system comprising an electron gun, a vacuum chamber, a working chamber and a manipulation system.

An electrode, a preparation method therefor, and uses thereof. Titanium or titanium alloy is used as a base material of the electrode, the outer surface of the base material is coated with a composite material coating, and the composite material coating is prepared by coating a composite material solution and carrying out drying and sintering. The composite material solution is a nanoscale solution formed by dissolving transition metal elements in ethanol. The nanoscale solution is an ethanol solution of the nanoscale transition metal with particles of the transition metal as solutes thereof. The transition metal elements are platinum, iridium, ruthenium, gold, cerium, rhodium, tantalum, manganese, nickel, palladium, yttrium, gadolinium, cobalt, europium, lanthanum, neodymium, zirconium and titanium, and the molar ratio of the transition metal elements platinum, iridium, ruthenium, gold, cerium, rhodium, tantalum, manganese, nickel, palladium, yttrium, gadolinium, cobalt, europium, lanthanum, neodymium, zirconium and titanium in the composite material solution is 5-15:23-34:14-21:1-7:9-17:3-12:15-27:3-6:2-9:10-23:15-27:2-8:15-30:3-12:4-14:1-10:6-15:20-50.

A method of installing a fixture or bracket in a fuselage structure of an aircraft or spacecraft. The method includes arranging an apparatus in, on or adjacent the structure, pre-treating a surface region of the structure by heat ablation using the apparatus and forming the fixture in situ on the structure at the pre-treated surface region using the apparatus based on a digital model of the fixture. The fixture is installed by connecting the fixture to the structure at the pre-treated surface region as the fixture is formed.

An additive manufacturing technique may include forming, on a surface of a substrate, a layer of material using an additive manufacturing technique. The material may include a sacrificial binder and a powder comprising an oxide-dispersion strengthened alloy dispersed in the binder. The technique may include forming, on the layer of material, at least one additional layer of material to form an additively manufactured component. The binder may be selectively sacrificed to leave the powder, for example, to form a component including an alloy.
