A plasma transfer wire arc thermal spray system includes a section for feeding a wire acting as a first electrode, a source of plasma gas providing plasma gas, a nozzle directing the plasma gas stream from the source of plasma gas to a free end of the wire, and a second electrode located in the plasma gas stream towards the nozzle. In certain instances, the nozzle is made at least partially of electrically insulating material. The thermal spray apparatus with the inventive spray gun may have a simplified and faster starting procedure and the spray nozzle can be more durable.

Plasma transfer wire arc thermal spray system

A brake drum for a vehicle includes a friction ring and a drum body. The friction ring has grooves arranged on a radial outer surface along a circumference, and a coating formed on the grooves. The drum body is cast onto the radial outer surface of the friction ring so that the grooves are filled with a material of the drum body. The grooves include first grooves and second grooves. A first axial segment is formed at the friction ring in which the first grooves are introduced so that the first grooves are inclined relative to a first axial end of the friction ring. A second axial segment is formed at the friction ring in which the second grooves are introduced so that the second grooves are inclined in a direction which is opposite to that of the first axial segment. Each of the grooves have undercuts.

Brake drum and method for producing such a brake drum

In one or more embodiments, the invention relates to a plasma transfer wire arc thermal spray system, comprising a section for feeding a wire acting as a first electrode, a source of plasma gas providing plasma gas, a nozzle directing the plasma gas stream from the source of plasma gas to a free end of the wire, and a second electrode located in the plasma gas stream towards the nozzle. In certain instances, the nozzle is made at least partially of electrically insulating material. The thermal spray apparatus with the inventive spray gun may have a simplified and faster starting procedure and the spray nozzle can be more durable.

The invention relates to a device for thermally coating a surface, which has at least one housing (), a cathode (), a primary gas distributor (), a secondary gas distributor (), electrically and thermally acting insulation elements (), and an anode, which is designed as a consumable wire and is guided into a nozzle () by means of a wire guide (), wherein the nozzle () is mounted in a centered manner and has openings () arranged radially in one plane on one of its sides ().

Plasma nozzle for thermal spraying using a consumable wire

The invention relates to a device for thermally coating a surface, which has at least one housing, a cathode, which is designed as a consumable wire and at least one insulation element, wherein the housing has a non-detachable anti-adhesion layer.

Device for thermally coating a surface

A method for roughening and thermally coating a surface, in particular a cylinder running surface of an internal combustion engine, the roughening being the preparation of the surface for the thermal coating of the surface with a coating. The method is characterized in that different roughening profiles are introduced into the surface during the roughening and the coating has different properties distributed over the surface. This allows the coating or spraying process during the later thermal coating to be carried out with substantially constant spraying parameters. The different properties of the coating, such as hardness, porosity, machinability, chemical composition, oxidation and adhesion, are then obtained just on the basis of the differently roughened surface.

Method for roughening and coating a surface

A device for the thermal coating of a surface, having a wire supply unit for the supply of a wire, wherein the wire acts as a first electrode, a source for plasma gas for generating a plasma gas stream, a nozzle body with a nozzle opening through which the plasma gas stream is conducted as a plasma gas jet to one wire end, and a second electrode which is arranged in the plasma gas stream before the latter enters into the nozzle opening The device is characterized in that the wire supply unit is adjustable, whereby the wire end situated in front of the nozzle opening can be moved by a certain adjustment travel. In this way, it is possible for installation tolerances in the device to be easily compensated, and high and consistent quality of the coating is attained.

A method of repairing an inner surface of a cylinder liner housed in an engine block. Material is removed from the inner surface to produce a reduced-thickness region, the reduced-thickness region extending axially relative to the cylinder and stopping short of an end of the liner to leave a region of original diameter between the reduced thickness region and the end of the liner. The surface the reduced-thickness region is then roughened, for example by hammer brushing. A plasma coating is applied to the reduced-thickness region and to at least a portion of the region of original diameter. The coating is then finish-machined to produce a uniform internal diameter equal to an original internal diameter of the region of original diameter prior to the application of the coating.
