The present disclosure relates to coated non-metallic substrates and coated metallic substrates and methods for producing such coated substrates. A variant of the method is characterized in that a mat or glossy coating is underneath a metallic layer obtained in some eases by way of vapor deposition and/or sputtering. In another variant, the metallic layer is sufficiently thin so that it remains transparent or translucent to visible light. The coated substrates may include multiple layers such as metallic layers, polysiloxane layers, a color layer, a conversion layer, a primer layer, and/or a transparent or colored layer. An application system for applying a metallic layer to at least one surface of a substrate may include a plasma generator and/or a corona system for treating one or more layers by plasma treatment and/or corona treatment.

A titanium-based component having a high heat capacity surface. The high heat capacity surface prevents or inhibits titanium fires. The component is titanium-based, forming the substrate, and includes a high heat capacity surface overlying the titanium substrate. A diffusion barrier is intermediate the titanium-based substrate and the high heat capacity surface. The diffusion barrier is non-reactive with both the titanium-based substrate and the high heat capacity surface. The system eliminates the formation of detrimental phases due to diffusion between the applied high heat capacity surface and the titanium substrate. The high heat capacity material has a coefficient of thermal expansion compatible with the coefficient of thermal expansion of the titanium-based substrate. The stresses introduced into the component as a result of differential thermal expansion between the high heat capacity material and the titanium-based substrate do not result in spalling of the substrate at the operational temperatures of the component.

A component for a turbomachine having at least one region made of an intermetallic material which is formed from an intermetallic compound or comprises an intermetallic phase as the largest constituent. The intermetallic material is compacted and/or modified in microstructure by microplasticization at least partially at a surface or interface in a region close to the surface or interface.

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 stabilizer elements to the surface and melting and resolidifying the surface. An average value of stabilizer element(s) concentration in a range of within 1 mm in depth is higher than 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 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 for producing a corrosion resistant metal substrate and corrosion resistant metal substrate provided thereby. The method involves forming a plated substrate including a metal substrate provided with a nickel layer or with a nickel and cobalt layer followed by electrodepositing a molybdenum oxide layer from an aqueous solution onto the plated substrate, which is subsequently subjected to an annealing step in a reducing atmosphere to reduce the molybdenum oxide in the molybdenum oxide layer to molybdenum metal in a reduction annealing step and to form a diffusion layer which contains nickel and molybdenum, and optionally cobalt.

The present invention is intended to provide a roll-bonded laminate, in which an ultrathin metal layer is laminated on another metal without generation of wrinkles, cracks and the like. A roll-bonded laminate formed by lamination of at least three layers, which comprises a peelable carrier layer 10, an ultrathin metal layer 20 and a metallic foil 30, wherein the thickness of the ultrathin metal layer 20 is 0.5 ?m or more and 20 ?m or less.

Bipolar wave current, with both positive and negative current portions, is used to electrodeposit a nanocrystalline grain size deposit. Polarity Ratio is the ratio of the absolute value of the time integrated amplitude of negative polarity current and positive polarity current. Grain size can be precisely controlled in alloys of two or more chemical components, at least one of which is a metal, and at least one of which is most electro-active. Typically, although not always, the amount of the more electro-active material is preferentially lessened in the deposit during times of negative current. The deposit also exhibits superior macroscopic quality, being relatively crack and void free. Parameters of current density, duration of pulse portions, and composition of the bath are determined with reference to constitutive relations showing grain size as a function of deposit composition, and deposit composition as a function of Polarity Ratio, or, perhaps, a single relation showing grain size as a function of Polarity ratio. A specified grain size can be achieved by selecting a corresponding Polarity Ratio, based on these relations. Coatings can be in layers, each having an average grain size, which can vary layer to layer and also in a region in a graded fashion. Coatings can be chosen for environmental protection (corrosion, abrasion), decorative properties, and for the same uses as a hard chrome coating. A finished article may be built upon a substrate of electro-conductive plastic, or metal, including steels, aluminum, brass. The substrate may remain, or be removed.

Compositions are provided that exhibit an austenitic nickel microstructure. The compositions comprise Ni, Cr, Mo and at least one element selected from the group consisting of Al, Si, and Ti. Feedstock having the composition may be in the form of a cored wire or wires, a solid wire or wires, or a powder.
