A process for coating a carrier material with an active material for production of an electrode foil of a battery cell with a Laval nozzle, wherein the Laval nozzle has at least one converging first portion, one second portion having a smallest flow cross section, and one diverging third portion arranged one after the other along a flow direction.

A rotary coating tool includes a rotary tool for coating bores and surfaces using solid-state deposition and consolidation of high velocity powder particles undergoing thermal plastic deformation.

A process for producing a layer or a body built up of layers. A process gas which has a pressure of >10 bar is accelerated in a convergent-divergent nozzle and a coating material which is formed by particles and is composed of Mo, W, an Mo-based alloy or a W-based alloy is injected into the process gas. The particles are at least partly present as aggregates and/or agglomerates. It is possible to produce dense layers and components in this way. We also describe layers and components having a microstructure with cold-deformed grains having a high aspect ratio.

A method for controlling gas dynamic spraying includes providing a particle jet by using an accelerating nozzle, illuminating the particle jet with illuminating light pulses, capturing images of the particle jet illuminated with the illuminating light pulses, and determining one or more velocity values by analyzing the captured images, wherein the images are captured by using an imaging unit which includes imaging optics to form an optical image of an object plane on an image sensor by focusing light, wherein an optical axis of the imaging unit is inclined with respect to a central axis of the nozzle, and wherein the image sensor is inclined with respect to the optical axis such that the object plane is substantially parallel with a direction of movement of particles of the particle jet.

Provided are a masking jig, a film formation method, and a film formation device that enable efficient formation of a film with consistent quality on the surface of a substrate. A masking jig is used in a thermal spraying method, and includes a body portion. The body portion includes a first surface and a second surface. The second surface is located on a side opposite to the first surface. The body portion has a through hole formed therethrough extending from the first surface to the second surface. The second surface includes inclined surfaces having inclination angles ?1 and ?2 of larger than or equal to 30? and smaller than 90? with respect to the first surface. An open end of the through hole in the second surface is formed in the inclined surfaces.

[Problem] To provide a corrosion-resistant coating that exhibits greater corrosion protection in saltwater environments and the like than was conventional, a method for forming the same, and a device for forming the same. [Solution] A corrosion-resistant alloy coating is formed on a substrate surface by: a) using a thermal spray gun, having a function wherein a flame including melted material particles is jetted toward a substrate, and the flame is partitioned from the open air in an upstream region on said jet path (which is to say the region in which the material particles are melted), and a function wherein, in a downstream region (the area continuing from the upstream region), the material particles and the flame are forcibly cooled by a jet-gas or jet-mist before reaching the substrate; and b) using a corrosion-resistant alloy material comprising aluminum, for the material particles.

A non-drip hygiene dispenser for dispensing a wipe paper-towel while keeping a clean and sterile working area comprises (a) a wipe paper-towel, (b) at least one reservoir containing liquid, (c) a first stream of compressed air, (d) a second stream of compressed air, an anti-dripping nozzle, (e) rolling means, and (f) cutting means. The anti-dripping nozzle further comprises activating means and a dispensing tip. The activating means comprises a retractable anti-drip needle backed by a spring. The spring retracts backwards when compressed air of the first stream of compressed air presses the spring, thus retracts the anti-drip needle, and thus, unblocks the dispensing tip to allow liquid from the at least one reservoir to flow through the dispensing tip. When the compressed air pressing the spring is released, the retractable anti-drip needle returns to its original place, blocking the dispensing tip to block the passage of liquid remained in the dispenser immediately upon shut off of the dispenser, thus, to avoid undesired dripping. The second stream of compressed air entering the anti-dripping nozzle mixes with the sprayed liquid in order to form a foggy environment around the wipe paper-towel.

A composite piezoelectric coating (CPC) method includes entraining a powder in a first carrier gas stream; heating a second carrier gas stream to a predetermined temperature; combining the first carrier gas stream and second carrier gas stream into a combined carrier gas stream; ejecting the combined carrier gas stream at a target at a predetermined velocity, and consolidating the powder on the target by impact of the ejected combined carrier gas stream with the target.

Apparatus, systems, and methods for identifying and quantifying chemical components in a high-melting-point liquid. One such method includes: receiving, into a nebulizer assembly, a high-melting-point liquid from a molten liquid conduit; aerosolizing, using the nebulizer assembly, at least a portion of the received high-melting-point liquid; delivering, into one or more instruments, the aerosolized high-melting-point liquid from the nebulizer; and chemically analyzing, using the one or more instruments, the aerosolized high-melting-point liquid.

Described herein, are methods for providing a protective coating to a storage container for storing nuclear material, the method comprising depositing nickel particles on at least one surface of the substrate to produce the protective coating, wherein the nickel particles are deposited by cold spraying a composition comprising nickel particles and a carrier gas comprising nitrogen. In one aspect, the carrier gas consists essentially or consists only of nitrogen. The methods do not require pretreatment or modification of the nickel particles prior to cold spraying, which makes the methods described herein economically practical. The coatings produced by the methods described herein possess several advantageous properties including, but not limited to, high adhesion strength to the storage system and low porosity. The coatings produced by the methods described herein are effective against chemical attack such as, for example, CISCC.
