Methods for forming particulates that are highly consistent with regard to shape, size, and content are described. Particulates are suitable for use as reference materials. Methods can incorporate actinides and/or lanthanides, e.g., uranium, and can be used for forming certified reference materials for use in the nuclear industry. Methods include formation of an aerosol from an oxalate salt solution, in-line diagnostics, and collection of particles of the aerosol either in a liquid impinger or on a solid surface.

A gas turbine engine article includes a substrate and an environmental barrier coating disposed on the substrate. The environmental barrier coating includes oxygen-scavenging particles. Each oxygen-scavenging particle includes a silicon-containing core particle encased in an oxygen barrier shell.

The cylinder rod of a hydraulic cylinder includes a body portion having a bar shape, and a head portion arranged at a longitudinal end of the body portion. The body portion has a coating formed on its outer peripheral surface. The coating includes, in terms of area ratio in cross section, not less than 56.1% and not more than 84.4% of a chromium carbide phase, with the remainder consisting of a nickel-based alloy phase and an oxide phase. The area ratio of the chromium carbide phase may be 61.7% or more.

The substrate for a printed circuit board according to an embodiment of the present invention includes a base film having insulating properties, and a metal layer stacked on at least one surface of the base film, in which the base film includes a portion where a transition metal in group 10 of the periodic table is present. The transition metal in group 10 is preferably nickel or palladium. The portion where the transition metal in group 10 is present preferably includes a region having an average thickness of 500 nm and extending from an interface with the metal layer.

Cobalt-based alloy compositions are described herein having properties compatible with thermal spray and sintering techniques. Such alloy compositions can provide claddings to a variety of metallic substrates having complex geometries, wherein the claddings exhibit desirable density, hardness, wear resistance and corrosion resistance. Briefly, an alloy composition described herein comprises 15-25 wt. % chromium, 15-20 wt. % molybdenum, 0-15 wt. % tungsten, 10-20 wt. % nickel, 2.5-3.5 wt. % boron, 2.5-4.5 wt. % silicon, 1-2 wt. % carbon and the balance cobalt, wherein a ratio of boron to silicon (B/Si) in the alloy composition ranges from 0.5 to 1.0.

A process for producing a titanium load-bearing structure, which comprises cold-gas dynamic spraying of titanium particles on to a suitably shaped support member, and a titanium load bearing structure so-produced.

An article of manufacture includes a part structure formed via a first additive manufacturing process and a floating structure within the part structure which is mechanically decoupled from the part structure. The floating structure is formed concurrently with the part structure via the first additive manufacturing process.

A wear-resistant coating film is disclosed that can maintain high wear resistance for a long period of time even when it is subjected to repetitive wear, and a method for producing the film, as well as a wear-resistant component. The wear-resistant coating film 10 includes a plated layer 11, lump parts 2, and a coat layer 13. The plated layer and the coat layer are laminated, and each of the lump parts is formed of a single particle 12 and/or an assembly of particles 12. The lump parts 2 are held by the plated layer 11 and are disposed to protrude from the plated layer 11. The coat layer 13 is formed to coat the surface of the plated layer 11, the lump parts 2 have flat portions 18, and the flat portions 18 are placed on the same plane as the surface of the coat layer 13.
