A method for fabricating a substrate provided with a plurality of layers, includes: providing a steel substrate with an oxide layer including metal oxides on the steel substrate; providing a metal coating layer directly on the oxide layer, the metal coating layer including: at least 8% by weight nickel; at least 10% by weight chromium; and a remainder being iron and impurities from a fabrication process; and providing an anti-corrosion coating layer directly on the metal coating layer.

A coated substrate, includes a coating that includes, starting from the substrate in this order: a) a layer of diamond-like carbon (DLC), b) a metallic, single-ply or multi-ply layer, and c) an oxygen barrier layer, wherein the metallic, single-ply or multi-ply layer contains b1) tin or tin and at least one alloying element for tin, which are present unalloyed and/or alloyed, or b2) magnesium and at least one alloying element for magnesium, which are present unalloyed and/or alloyed. The coated substrate protects the DLC layer, as a result of which said layer can be tempered. The coating has good mechanical stability and good aging stability before heat treatment.

A flat steel product for hot forming may be produced from a steel substrate that includes a steel comprising 0.1-3% by weight Mn and up to 0.01% by weight B, along with a protective coating that is applied to the steel substrate. The protective coating may be based on Al and may contain up to 20% by weight of other alloy elements. Also disclosed are methods for producing such flat steel products, steel components, and methods for producing steel components. Absorption of hydrogen is minimized during heating necessary for hot forming. This is achieved at least in part through an alloy constituent of 0.1-0.5% by weight of at least one alkaline earth or transition metal in the protective coating, wherein an oxide of the alkaline earth or transition metal is formed on an outer surface of the protective coating during hot forming of the flat steel product.

Superalloy workpiece including a superalloy substrate and an interface layer (IF-1) of essentially the same superalloy composition directly on a surface of the superalloy substrate, followed by a transition layer (TL) of essentially the same superalloy and supperalloy oxides or a different metal composition and different metal oxides whereby oxygen content of the transition layer is increasing from IF-1 towards a barrier layer (IF-2) of super alloy oxides or of different metal oxides.

An engineered substrate includes a support structure comprising a polycrystalline ceramic core, an adhesion layer coupled to the polycrystalline ceramic core, and a barrier layer coupled to the adhesion layer. The engineered substrate also includes an bonding layer coupled to the support structure, a substantially single crystal layer coupled to the bonding layer, and an epitaxial gallium nitride layer coupled to the substantially single crystal layer.

A method for producing an elastic wave device includes steps of (a) preparing a first substrate and a second substrate, (b) irradiating a bonding surface of the first substrate and a bonding surface of the second substrate with one of plasma, neutral atom beams, and ion beams of an inert gas, (c) bonding the bonding surface of the first substrate and the bonding surface of the second substrate in a vacuum at room temperature so as to set a strength that allows the first and second substrates to be separated by insertion of a blade; (d) forming a composite substrate by bonding a piezoelectric substrate to another surface of the first substrate; (e) forming electrode on a surface of the piezoelectric substrate of the composite substrate; and then (f) removing the second substrate from the first substrate by separation with the blade.

Substrate provided with a plurality of layers, at least one of which includes metal oxides and is topped directly by a metal coating layer that contains at least 8% by weight nickel and at least 10% by weight chromium, the remainder being iron, additional elements and the impurities resulting from the fabrication process, wherein this metal coating layer is topped directly by an anticorrosion coating layer. A corresponding fabrication method is also provided.

A superalloy target wherein the superalloy target has a polycrystalline structure of random grain orientation, the average grain size in the structure is smaller than 20 m, and the porosity in the structure is smaller than 10%. Furthermore, the invention includes a method of producing a superalloy target by powder metallurgical production, wherein the powder-metallurgical production starts from alloyed powder(s) of a superalloy and includes the step of spark plasma sintering (SPS) of the alloyed powder(s).

Certain example embodiments relate to a coated article including at least one infrared (IR) reflecting layer of a material such as silver or the like in a low-E coating, and methods of making the same. In certain cases, at least one layer of the coating is of or includes nickel and/or titanium (e.g., Ni.sub.xTi.sub.yO.sub.z). The provision of a layer including nickel titanium and/or an oxide thereof may permit a layer to be used that has good adhesion to the IR reflecting layer, and reduced absorption of visible light (resulting in a coated article with a higher visible transmission). When a layer including nickel titanium oxide is provided directly over and/or under the IR reflecting layer (e.g., as a barrier layer), this may result in improved chemical and mechanical durability. Thus, visible transmission may be improved if desired, without compromising durability; or, durability may simply be increased.
