A composite object for the production of hydrogen from water-reactive aluminum may include a first portion including an aluminum alloy having a non-recrystallized grain structure, and a second portion including an activation metal corrodible to the aluminum alloy, wherein the second portion and the first portion are coupled to one another with the activation metal of the second portion in contact with the aluminum alloy of the first portion at a plurality of points of contact stress, and the activation metal of the second portion is penetrable into the non-recrystallized grain structure of the aluminum alloy of the first portion via the addition of heat.

Reinforced diamond nozzles and methods of making the same for fluid jet cutting applications are provided. An example method includes forming or providing a tubular diamond body having a jet passage extending therethrough and establishing a protective casing around the tubular diamond body so that an entirety or substantially an entirety of an outer circumferential surface area of the tubular diamond body is directly contacted and reinforced by the protective casing. Establishing the protective casing around the tubular diamond body may include thermal spraying, casting, direct metal laser sintering, or other fabrication techniques.

A method for working a wall of a cylinder of an internal combustion engine, in which peripheral grooves are machined into the wall, wherein at least one annular saw blade, which is provided on a circumference with a multiplicity of cutting teeth, is used for introducing the grooves, wherein the saw blade is moved so as to rotate about its longitudinal axis and on an annular path. A subsequent forming operation on the lands that are formed between neighboring grooves causes the formation of undercuts that can improve the connection of the wall of the cylinder to a subsequently applied coating layer.

Provided are a system and process for remanufacturing a waste cylinder assembly of an aircraft piston engine. The spraying apparatus includes a first power mechanism, a spray gun assembly and a second power mechanism. The first power mechanism drives the cylinder assembly to move in a horizontal direction and a vertical direction. The second power mechanism drives the spray gun assembly to rotate around a center of the blind hole and ensures that prepared coatings can be evenly distributed along an inner wall of the blind hole. A nozzle end of the spray gun extends into the blind hole, and the spray gun is adjustable relative to the center of the blind hole. A spraying distance is not fixed so as to change the spraying distance. Powder can be fully melted.

The present disclosure provides a method, system, and apparatus that adds one or more reinforcing structures to a thermally sprayed layer of metallic material onto a substrate to reinforce and/or further support the formed substrate coating. The reinforcing structure may be a metallic or non-metallic wire, filament, whisker, mesh, or similar structure and may be coupled to the substrate before or during the thermal spray process, thereby embedding the reinforcing structure(s) into the resulting thermal spray matrix. The type, material, size, shape, and application technique of the reinforcing structure is variable based upon the desired characteristics of the ultimate coating. The durable coating may be formed by a plurality of separate and/or distinct layers. The resultant coating (e.g., the reinforcing structure(s) with the one or more thermal spray layers) provides numerous benefits, including increased strength and resistance to spalling, breaking, cracking, deforming, crack formation, and corrosion.

A method of manufacturing a jacketed metal line is detailed herein. The method of manufacturing a jacketed metal line can include roughening an outer surface of a metal core of the line. An insulating polymer layer can be applied to the metal core, and the insulating polymer layer can include a reinforcing additive comprising: graphite, carbon, glass, aramid, short-fiber filled PolyEtherEtherKetone, mircron-sized polytetrafluoroethylene, or combinations thereof. The roughened metal core can then be exposed a heat source for at least partially melting the polymer layer; and the partially melted polymer layer and insulated roughened metal core can be ran through a set of shaping rollers.
