Abstract:
The present invention relates to a method of coating at least one section of the surface (2) of a plastic or composite part with a layer (6) of an additive material. That section of the surface (2) of the part that is to be coated is pre-treated by degreasing, evening out, roughening, degreasing and drying in that order. A layer (4) of a thermosetting adhesive is then applied to the said section of the surface (2) of the part. Before coating is carried out, the adhesive layer (4) is heated to a temperature approaching its gel point. The surface is then coated by thermal spraying with a layer (6) of an additive material. After coating, the part (1) is heated to the setting temperature of the adhesive layer, causing this to set. The invention also relates to a product (1) of a plastic or composite material manufactured by the method in which at least one section of its surface (2) is coated with a layer (6) of an additive material.
Abstract:
A conical inductively coupled plasma (ICP) torch (100) and a method for processing sample particles is disclosed. In this method raw, unprocessed, irregularly shaped sample particles (21) are injected into the conical torch, and pass through the plasma to form molten particles (22) and a spheroidization of the particles finally generates solid, smooth, spherical and dense processed particles (23) once cooled. The conical torch has a torch tube that has a conical section and an injector tube (2) that has a conical end. The conical section of the torch tube and the injector tube form an annular gap through which outer plasma gas is passed through. This conically exiting outer gas flow results in a rapid rise in gas temperatures and a short plasma region that rapidly melts any particles.

Eine Vorrichtung zur Beschichtung zumindest einer Faser, mit beispielsweise zumindest zwei Plasmaspritzeinrichtungen zum Einbringen von mit einem Plasma aktivierten Pulverteilchen in einen Beschichtungsbereich. Des Weiteren kann die Vorrichtung eine Pulverfördereinrichtung zum Bereitstellen von Pulverteilchen zu den zumindest zwei Plasmaspritzeinrichtungen und eine Fasertransporteinrichtung aufweisen, die ausgebildet sein kann, die zumindest eine zu beschichtende Faser durch den Beschichtungsbereich zu führen, um eine Beschichtung der zumindest einen Faser mit den aktivierten Pulverteilchen in dem Beschichtungsbereich zu bewirken. Die zumindest zwei Plasmaspritzeinrichtungen können in einem Winkel und/oder in einer Längsrichtung, der zumindest einen Faser, zueinander versetzt angeordnet sein und auf den Beschichtungsbereich gerichtet sein.
Abstract:
A laser cladding deposited on a metal component protects the metal component against wear and tear. The laser cladding includes an alloy matrix having carbide hard particles embedded within or bonded with the alloy matrix. Induction heaters pre-heat the metal components during the laser cladding process to inhibit cracking of the alloy when the carbide particles are injected. The heaters provide simultaneous induction heating to the external surface of the metal components.
Abstract:
A surface treatment device that ejects a combination of precursor substances as a directed flow of surface treatment particles. Planar objects are conveyed along a defined plane through the particle flow, a region on the surface of the planar object that the particle flow hits forming a region of direct impact. The device comprises directing means for directing the particle flow to travel along the surface of the planar object in an extended impact region outside the region of direct impact; and flow control means for controlling the extent of the extended impact region which may include a vortex flow. The exposure of the treated surface with the particle flow increases and the probability of the desired surface treatment processes to take place increases.
Abstract:
It has been surprisingly found that injecting ceria-based particles (mean size less than 200nm) suspended in a combustible organic solvent into a plume having a maximum temperature between about 2,600°C and 4,000°C to impart a mean temperature to the particles from about 2,600°C to about 3,800°C, and to accelerate the particles to a mean velocity between about 600 to 1000 m/s, produces a thin, uniform, dense, crack-free, nanocrystalline ceria-based coating, which may be applied on porous cermet or metal substrate, for example. The physical environment of a high-velocity oxy-fuel (HVOF) thermal spraying gun suitably deployed using standard fuels produces these conditions. The method of the present invention is particularly useful for the cost-effective fabrication of ceria-containing electrolytes for solid oxide fuel cells (SOFCs).
