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 m/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.

Method for cold gas spraying

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.

Method and apparatus for thermal spraying

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.

Method for manufacturing diamond

A method for producing a pipe, a carrier element being coated by means of a thermal spraying method, the material of the pipe formed later being selected as the coating material, and the coating forming the pipe being detached from the carrier element, the spraying angle, at which the coating material is sprayed onto the carrier element, being selected such that a low level of adhesion of the coating on the carrier element is achieved.

Method for producing a pipe

A high-pressure gas-heating device has a pressurized container () carrying a gas, a heating element () arranged in the pressurized container (), and an insulation (). The insulation () is arranged on the interior wall of the pressurized container (). The pressurized container () is designed for pressures of to 100 bar, and at least one flow distributor element () is arranged in an inflow area of the pressurized container () to distribute the inflowing gas over the entire width of the heating element ().

High-pressure gas heating device

A cold gas spray gun is disclosed. The spray gun includes a high-pressure gas heater which has a pressure vessel through which gas flows and a heating element situated in the pressure vessel, as well as a mixing chamber in which particles can be admixed with the gas through a particle feed. A Laval nozzle is arranged downstream in the direction of flow of the gas and consists of a convergent section, a nozzle throat and a divergent section. The high-pressure gas heater and/or the mixing chamber is/are at least partially insulated on the inside in the areas of contact with the gas.

Cold gas spray gun

A cold gas spraying method and device, whereby the sprayed particles are accelerated in a gas flow. A powder tube and an outer nozzle body together form a Laval nozzle that produces high gas flow velocities. The injection of the sprayed particles occurs in the divergent section of the Laval nozzle.

Method and system for cold gas spraying

A thermal spray coating method for creating a coating layer on a surface of a substrate is monitored by determining characteristics of the thermal spray coating as it affects the quality of the coating layer by recording, controlling, and monitoring through a digital camera whose image is analyzed and characterized.

In order to increase the useful life of a golf club, at least part of the golf club in a region of the striking face is coated with a coating that is neutral in terms of stress or has compressive stresses. The coating is applied by a thermal spraying method with average spray-particle velocities of over 500 m/s. The coating preferably has compressive stresses of between 0 and 600 MPa.

Golf club with stress-specific striking face and method of producing the coating

The invention relates to a golf club with a striking surface for striking golf balls. The golf club has a coating applied by a thermal spray method at least in the area of the striking surface. The club coatings are preferably applied by a high-speed flame spray method or by a cold gas spray method. For coating golf clubs by hot spraying, in particular metals, metal alloys, oxides, (especially Al O and/or TiO ), carbides, borides, plastics, or mixtures of the above substances can be used as the spray materials.
