Abstract:
A method for coating the core ceramic particles by emulsion flame spray is provided. In particular, the method forms a core ceramic particle simultaneously with coating the surface of the formed core ceramic particles by emulsion flame spray pyrolysis. The core ceramic particle may be coated in a single stage by emulsion flame spray pyrolysis conventionally used in the art, through putting coating material precursor into the oil phase of emulsion solution at a stage of preparing emulsion solution in emulsion flame spray pyrolysis process.

Abstract:
A plasma coating system includes at least one coating station with a first side and a second side defining a pathway with at least one bend. The coating station also includes a first plasma arc that provides a plasma jet directed towards a substrate. The first plasma arc is positioned on either the first side or the second side of the bend.
Abstract:
A zinc-nickel substrate is applied to a component by using a zinc-nickel wire formed with between about 8 to 20 percent nickel and between about 80 to 90 percent zinc. This formed zinc-nickel wire is held in a two wire electric arc spray system to spray the zinc-nickel substrate on the component, such as an aircraft part, while operating the two wire electric arc spray system within a specific range of operating parameters.
Abstract:
In a method for the production of a gradient encapsulation layer 20 on a piezoelectric actuator 1, based on this gradient encapsulation layer 20, the piezoelectric actuator 1 does not 5 require an additional housing-like enveloping structure in order to be protected externally. The gradient encapsulation layer 20 is produced by cold gas spraying of particles having different material properties.
Abstract:
This disclosure relates to a thermal spray coating system including a table that is configured to support a component. A spray torch is configured to direct a thermal spray at a component surface. A cooling device is arranged adjacent to spray torch and configured to be in close proximity to the component surface. The cooling device includes a manifold that is connected to an air supply. The manifold has a face with multiple impingement holes less than one-eighth inch (3.1 mm) in diameter that are configured to direct cooling air on the component surface. In one example, the diameter of the impingement holes is approximately 0.059 inch (1.5 mm) and provide cooling air at a velocity of at least 400 ft per second (122 meters per second). The face is arranged within one inch (25 mm) of the component surface, in one example. Accordingly, the above cooling device uses less air and yields more consistent results in thermal coating of the component.
Abstract:
A blade for creping a paper web from a dryer surface is provided, said blade having a sliding surface facing the dryer surface during use of the blade, a web impact surface upon which the paper web impacts during creping, and a working apex formed between the sliding surface and the web impact surface, wherein the working apex is located no more than 30 percent of the total blade thickness away from a neutral fiber of the blade. Preferably, the working apex of the inventive creping blade is located at or close to the neutral fiber of the blade. A method for manufacturing the blade is also disclosed.
Abstract:
Thermal spray processing and cold spray processing are utilized to manufacture porous starting materials (such as tube stock, wire and substrate sheets) from biocompatible metals, metal alloys, ceramics and polymers that may be further processed into porous medical devices, such as stents. The spray processes are also used to form porous coatings on consolidated biocompatible medical devices. The porous substrates and coatings may be used as a reservoir to hold a drug or therapeutic agent for elution in the body. The spray-formed porous substrates and coatings may be functionally graded to allow direct control of drug elution without an additional polymer topcoat. The spray processes are also used to apply the drug or agent to the porous substrate or coating when drug or agent is robust enough to withstand the temperatures and velocities of the spray process with minimal degradation.
Abstract:
A non-stick surface comprising a porous, hard metal-ceramic coating such as chromium oxide applied to the cook surface of a cooking utensil by arc or plasma spraying. The pores of the coating are impregnated under vacuum with an inert release agent of low viscosity such as food grade liquid silicon resin. After vacuum impregnation, the impregnate is thermally cured and the cook surface is mechanically abraded/polished to remove the protruding peaks of metal-ceramic material to expose flattened bare metal portions interspersed between and substantially co-planar with the surfaces of the impregnated release agent residing in the valleys/pores.
Abstract:
Apparatuses and methods for preventing the degradation of one or more mask materials during a thermal surface treatment process of a substrate having the steps of mounting at least one mask comprising one or more mask materials onto a substrate; thermally surface treating a surface of the substrate which increases the temperature of the substrate; and cooling the one or more mask materials with cryogenic fluid from at least one cooling means directed at the substrate.
