A joined material and a method of manufacturing the joined material are provided which enable a metal layer and a carbon material layer to be easily joined to each other while making the thickness of the metal layer larger and which can inhibit failure. A joined material includes a CFC layer (3) and a tungsten layer (4) that are joined to each other. A sintered tungsten carbide layer (5), a mixed layer (6) of SiC and WC, and SiC and WC (7) that have been sintered while intruding into the CFC layer (3), are formed between the CFC layer (3) and the tungsten layer (4), and these layers (3, 4, 5, 6, and 7) are joined to each other by sintering.

A molded resin product includes a design layer including a decorative layer having a first color, a shielding layer having a second color different from the first color, and a resin base layer. A cover layer formed of a polymer film is disposed close to one end of the design layer. Part of the decorative layer exposed from the shielding layer serves as an exposed region. The exposed region and part of the shielding layer constitute a pattern portion presenting a predetermined figure or character when viewed in plan through the cover layer. The rest of the shielding layer constitutes a base portion. The layer thickness of the base portion is set smaller than the layer thickness of the pattern portion in a region thereof where the shielding layer is formed.

A method of manufacturing a substrate (16) with a ceramic thermal barrier coating (28, 32). The interface between layers of the coating contains an engineered surface roughness (12, 24) to enhance the mechanical integrity of the bond there between. The surface roughness is formed in a surface of a mold (10,20) and is infused by a subsequently cast layer of material (16, 28). The substrate may be partially sintered (76) prior to application of the coating layer(s) and the coated substrate and coating layer(s) may be co-sintered to form a fully coherent strain-free interlayer.

The present invention is a laminate sheet having two laminae. The first lamina is a relatively hard material having first and second surfaces. The first surface has a plurality of raised and generally pointed piercing structures, each structure having a tip. The second lamina is graphite foil material, which is mated to the relatively hard material, such that at least some of the piercing structures pierce the graphite foil material. In one embodiment, the first lamina has no performations and is uniformly smooth. In another embodiment, the second surface also has a plurality of piercing structures and a third lamina comprising graphite foil is mated to the second surface.

A coated panel for a gas turbine engine includes a panel having a panel inner surface and a pocket formed in the panel inner surface, the pocket having a pocket depth. A coating is applied to the pocket such that a coating edge is disposed within the pocket to enhance coating retention to the panel. A gas turbine engine includes a turbine, a combustor to supply hot combustion gases to the turbine along a gas path, and one or more coated panels located along the gas path. The one or more panels includes a panel having a panel inner surface, and a pocket formed in the panel inner surface, the pocket having a pocket depth. A coating is applied to the pocket such that a coating edge is located within the pocket to enhance coating retention to the panel.

A cover layer formed of a polymer film is disposed close to one end of the design layer. Part of the decorative layer exposed from the shielding layer serves as an exposed region. The exposed region and part of the shielding layer constitute a pattern portion presenting a predetermined figure or character when viewed in plan through the cover layer. The rest of the shielding layer constitutes a base portion. The layer thickness of the base portion is set smaller than the layer thickness of the pattern portion in a region thereof where the shielding layer is formed.

The present specification relates to a joint body of different materials, and a method of manufacturing the same. The joint body includes a metal layer; and a resin layer provided on and in contact with one surface of the metal layer. The metal layer comprises two or more etching grooves and two or more burrs provided on a surface of the metal layer adjacent to the etching grooves.

A transparent composite armor is made of tens to hundreds or even thousands of thin layers of material each with a thickness of 10-500 m. An appropriate amount of impedance mismatch between the layers causes some reflection at each interface but limit the amplitude of the resulting tensile wave below the tensile strength of the constituent materials. The result is an improvement in ballistic performance and that will result is a significant impact in reducing size, weight, and volume of the armor.

A system and method of forming a wear resistant composite material includes placing a porous wear resistant filler material in a mold cavity and infiltrating the filler material with a matrix material by heating to a temperature sufficient to melt the matrix material, then cooling the assembly to form a wear resistant composite material. The system and method can be used to form the wear resistant composite material on the surface of a substrate, such as a part for excavating equipment or other mechanical part. One suitable matrix material may be any of a variety of ductile iron alloys.

A method of manufacturing a grain oriented electrical steel sheet includes subjecting a steel slab to a rolling process including cold rolling to obtain a steel sheet with a final sheet thickness, the steel slab containing by mass % C: 0.01% to 0.20%, Si: 2.0% to 5.0%, Mn: 0.03% to 0.20%, sol. Al: 0.010% to 0.05%, N: 0.0010% to 0.020%, at least one element selected from S and Se in a total of 0.005% to 0.040%, and the balance including Fe and incidental impurities; forming, by a chemical process, a linear groove extending in a direction forming an angle of 45 or less with a direction orthogonal to a rolling direction of the steel sheet; subjecting the steel sheet to decarburization annealing; applying an annealing separator thereon mainly composed of MgO; and subjecting the steel sheet to final annealing to manufacture a grain oriented electrical steel sheet.
