Abstract:
An apparatus and methods for cold spraying with a spraying unit, a particle supply, a gas supply, and at least one heating unit. The heating unit contains a graphite felt that can be heated with an electric heater current, through which a gas stream can flow, wherein the at least one heating unit is arranged separately and/or in a pressure tank through which the gas stream can flow.
Abstract:
A method for producing an armor plating for protected vehicles is described. The method employs the following steps: supplying a substrate made of a metal and/or a nonmetal and coating the substrate with the aid of a thermal spraying process. A device for producing an armor plating is also described herein.
Abstract:
The invention relates to a method for cold gas spraying in which a spray powder containing photocatalytically active spray particles is accelerated by means of a carrier gas in a nozzle and forms a coating upon striking a substrate. According to the invention, the method is characterized in that at least one part of the photocatalytically active spray particles consists of nanocrystalline agglomerates having a porosity of 200 to 800 m2/g, the porosity being determined by means of a BHT measurement with nitrogen. Coatings produced with the method according to the invention and objects having such a coating are also claimed.

Abstract:
A method for arc spraying in which at least one wire-shaped spray filler material is melted in an arc by means of electric current and atomised by means of an atomising gas flow and applied in the form of a particle stream onto a workpiece, at least one wire-shaped spray filler material being preheated before the melting in the arc.
Abstract:
In a method of producing a casting, molding or pressing tool (1) or tool insert (2) with at least one material layer (3, 5, 7) and with temperature control medium channels (6) arranged in the at least one material layer (3, 5, 7), the temperature control medium channels (6) are introduced into the at least one material layer (3, 5, 7) using a thermal spray process (2).
Abstract:
A method for manufacturing diamond or diamond-like carbon (DLC) by converting at least one other form of carbon such as graphite, amorphous carbon, fullerenes, glass carbon, graphene, carbon foam or a mixture of these forms. This method comprises an acceleration of particles and causing them to collide with a substrate. The particles and/or the substrate contain(s) or consist(s) of one other form of carbon. The conversion is induced by impact of the particles with the substrate, wherein cold gas spraying is used to advantage.
