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.

Homogeneous and transparent protective coatings for precious metals and copper alloys and techniques for forming the coatings on precious metals and copper alloys are provided. In an embodiment, ionic oxide film is deposited onto a surface of a substrate including a metal, such as a precious metal and/or a copper alloy, using pulsed chemical vapor deposition (PCVD). A homogenous and transparent solid film based on ionic oxide is formed on the surface of the substrate in response to the depositing.

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.

A filler disposition film that can use a commercially procurable filler material having good particle diameter uniformity, enables high positional precision of the filler disposition, can support even an increase in the surface area, and has a prescribed filler regularly disposed in a long resin film. Moreover, the rate of consistency of disposition of the filler in the filler disposition film in rectangular areas of a prescribed size having a length of 1000 times or more the average particle diameter of the prescribed filler, and a width of 0.2 mm or greater is 90% or greater. Such a rectangular area has a long-side direction that is substantially parallel to the long-side direction of the filler disposition film, and a widthwise direction that is substantially parallel to a short-side direction of the filler disposition film. The average particle diameter of the regularly disposed filler is from 0.4 μm to 100 μm.

A frangible laminate includes first, second and third webs, and the second web is positioned between the first and third webs. The forming of the frangible laminate includes adhesively bonding a first plurality of sections of the second web to the first web, applying release material in order to inhibit at least some of any bonding between the first plurality of sections of the second web and the third web, and adhesively bonding a second plurality of sections of the second web to the third web. The frangible laminate is separated into a first laminate and a second laminate, so that the first laminate includes the first web and the first plurality of sections of the second web, and the second laminate includes the third web and the second plurality of sections of the second web.

This application relates to a composite part that can include a non-metal layer having attachment features, and a metal part that is joined with the non-metal layer. The metal part can include a plurality of interlocking structures that are disposed at an external surface of the metal part, where each of the interlocking structures can include an opening characterized as having a first width, and an undercut region, where the opening leads into the undercut region, and the undercut region is characterized as having a second width that is greater than the first width such that the undercut region captures and retains one of the attachment features of the non-metal layer.
