Abstract:
Provided is a thermal spraying apparatus that forms a film on a target by thermally spraying a conductive powder by plasma, the thermal spraying apparatus including: a first electrode provided with a first cavity through which the conductive powder from a powder supplier passes; and a second electrode provided with a second cavity through which the conductive powder from the first electrode passes, in which the plasma is generated between the first electrode and the second electrode.
Abstract:
This disclosure provides an apparatus, system, and method for thermal spraying a metal cladding on a substrate. The apparatus may include a housing having a first electrode and a second electrode disposed in the housing. The second electrode can be spaced apart from the first electrode. The apparatus includes a first contact tip removably attached to the first electrode and a second contact tip removably attached to the second electrode. The position of the first contact tip and second contact tip is configured to be selectively adjusted on the first electrode and the second electrode to provide a plurality of contact surfaces for a feedstock wire. The apparatus includes a nozzle between the first contact tip and the second contact tip. The first contact tip and the second contact tip are configured to contact and deflect a wire towards the nozzle.
Abstract:
Disclosed are a display screen of an image display system capable of displaying a 3D (three-dimensional) image and providing an image with a high contrast ratio in a bright room and a method for manufacturing the same. The display screen includes: a Fresnel lens layer; a reflective layer formed the light-exit surface of the Fresnel lens layer to reflect image light; and a protection layer formed on the light-incident surface of the Fresnel lens layer, wherein one surface of the protection layer may have an embossed pattern.
Abstract:
Die vorliegende Erfindung betrifft ein Verfahren zum schichtweisen Herstellen und/oder Beschichten eines Werkstücks (200) mittels Metallschutzgasschweißens sowie eine entsprechende Vorrichtung zum schichtweisen Herstellen und/oder Beschichten eines Werkstücks (200) mittels Metallschutzgasschweißens, wobei eine abschmelzende Drahtelektrode (110) durch einen Lichtbogen (120) aufgeschmolzen wird und wobei aufgeschmolzenes Elektrodenmaterial (111) sich von der Drahtelektrode (110) ablöst, auf das Werkstück (200) übergeht und dort eine Schicht des Werkstücks (200) bildet, wobei eine nicht-abschmelzende Gegenelektrode (300) angeordnet wird, wobei der Lichtbogen (120) zwischen der Drahtelektrode (110) und der Gegenelektrode (300) gezündet wird und brennt und wobei die Gegenelektrode (300) am Ende der Schutzgasdüse (130) befestigt wird und damit ein im Wesentlichen geschlossene Raum von der Schutzgasdüse (130) und der Gegenelektrode abgegrenzt wird, wobei das Schutzgas durch die wenigsten eine Öffnung (310) in Richtung des Werkstückes (200) fließt.
