Abstract (en)

[origin: WO2006032522A1] The invention relates to a method for producing an arc-erosion resistant coating, in particular for the interior regions of arcing chambers that are exposed to electric arcs, and to a shield for vacuum arcing chambers that is produced according to said method, in accordance with the general terms of claims 1 and 10. The aim of the invention is to provide a simple method for producing arc-erosion resistant shields, which nevertheless results in practice in an extremely high arc-erosion resistance. To achieve this, a substrate material is provided with an arc-erosion resistant coating in a cold gas injection process.
