A slurry formulation for production of a patch or a strip of a thermal barrier coating includes 20-60 dry weight percent of alkali metal silicate binder, 40-80 dry weight percent of ceramic fillers including at least one ceramic filler selected from the group consisting of yttria-stabilized zirconia and magnesia, 0-20 dry weight percent of additives, wherein the dry weight percent of the alkali metal silicate binder, the ceramic fillers and the additives add up to 100%, and one of a solvent and suspension agent.

Slurry formulation for the production of thermal barrier coatings

The invention relates to a process for manufacturing a conductor bar comprising a number of partial conductors, with the following steps:

Method for producing a bar-type conductor

A powder-spraying appliance for electrostatic powder coating of work pieces. In order to achieve particularly good charging of powder particles, the powder-spraying appliance contains a chamber, into which a powder/air mixture is introduced transversely to a spraying direction via a supply conduit. An earth electrode and a plurality of high-voltage electrodes are disposed in the chamber. All of the electrodes are flushed with cleaning air in order to avoid powder deposits on the electrodes.

Powder-spraying appliance

A method and an apparatus for powder spraying can be used, for example, for electrostatic enameling. In order to achieve an easily regulatable high powder output rate, it is proposed to fluidize powder in a closed container, extract it in the region of the fluid bed and cause it to emerge through a nozzle on the container. The container is subdivided by a frit into a first chamber to which air is fed and a second chamber which contains the powder and out of which air is discharged through a valve. A powder output rate can be regulated by the regulation of air pressures.
