Disclosed is a method for creating a textured press plate. Initially, a mask may be applied to a surface of a press plate. This mask typically corresponds to a desired physical surface structure. Thereafter, the masked surface of the press plate is processed to obtain the desired physical surface structure. Thereafter, various techniques may be used to create differing degrees of gloss in differing portions of the surface of the press plate. For example, matting may be used to decrease the degree of gloss of a portion of the surface, and polishing may be used to increase the degree of gloss of a portion of the surface.

The present invention relates to a method for manufacturing a bump structure capable of enhancing adhesion, comprising the steps of: forming an under bump metal (UBM) layer on a conductive pad; forming a copper bump on the UBM layer by electrolytic plating; forming a nickel bump on the copper bump by electrolytic plating; forming a first gold bump on the nickel bump by electrolytic plating using a first gold plating solution; and forming a second gold bump on the first gold bump by electrolytic plating using a second gold plating solution, wherein the second gold plating solution contains thallium (Tl) and the first gold plating solution is free of thallium.

A method of making an article using an additive manufacturing technique includes depositing a powder. The powder includes particles formed from an article material and having particle surfaces. A coating formed from a sacrificial coating is deposited over the particle surface. The sacrificial material has a composition that is different from the composition of the article material and is separated from the article material during fusing of the article material into a layer of an additively manufactured article.

Methods of plating a metal on a substrate including coating a nanoporous metal-oxide layer on a surface of the substrate prior to metal plating. Methods may include coating a surface of the substrate with a slurry including colloidal metal-oxide precursor particles and aluminum oxide particles. After coating, the slurry may be calcinated on the surface of the substrate to form a nanoporous metal-oxide layer on the surface. Then, a metallic film may be plated on the nanoporous metal-oxide layer. The metallic film may be plated by an electroless plating method and/or an electroplating method. Articles, such as electronic interposers, may be made using the methods of plating a metal described herein.

A black plated resin part includes a resin substrate, an underlying plating layer formed on the resin substrate, and a black chromium plating layer formed of trivalent chromium and having a thickness of 0.15 m or more. The black chromium plating layer is formed on the underlying plating layer. The chromium in the black chromium plating layer is present in the form of metallic chromium, chromium oxide, and chromium hydroxide, and the black chromium plating layer exhibits a b* value of 3.0 or less based on the L*a*b* color system.

A method for preventing corrosion of an impeller-shaft assembly of a turbomachine comprises the steps of assembling an impeller on a shaft in order to define an impeller-shaft assembly; plating the assembly by inserting the assembly into a plating bath; and coating at least a first predefined surface on the impeller and a second predefined surface on the shaft wherein the coating step is performed by spraying the predefined surfaces.

A method comprising: creating first conductive traces over a substrate by selective creation of metallization over the substrate using selective direct structuring of a material configured for selective direct structuring; and creating second conductive areas over the substrate directly in contact with at least parts of the first conductive traces.

Strands of material may be intertwined using weaving techniques, knitting techniques, non-woven or entanglement techniques, or braiding techniques. Fabric that is formed from the strands of material may be used in forming a fabric-based item. The fabric based item may include electrical components. The strands may include conductive strands that form signal paths. The signal paths can carry electrical signals associated with operation of the electrical components. Each strand may have an elongated core and a coating. Strands may also include intermediate layers between the cores and coatings. The cores, intermediate layers, and coatings may be formed from polymer without conductive filler, polymer with conductive filler, and/or metal. A polymer core may be provided with recesses to help retain subsequently deposited layers such as a metal coating layer. The recesses may be grooves that extend along the longitudinal axis of the core.

A method of manufacturing a gas turbine engine air seal comprising forming at least one MAX phase particle. The method includes coating the at least one MAX phase particle with a metallic shell. The method includes applying the at least one MAX phase metallic coated particle to a surface of a substrate of the air seal to form an abradable layer of a MAXMET composite abradable material from the at least on MAX phase metallic coated particle.
