Process for applying a protective layer to a turbine component |
摘要 |
A turbine component is provided, on which a protective layer is arranged, for example to avoid droplet impact erosion, wherein, in a first method step, a nanofilm is applied and a brazing metal is applied to the nanofilm, and the nanofilm chosen is one which, after initial ignition, leads to an exothermic reaction, whereby fusion of the brazing metal with the base material takes place to form a protective layer. |

1. A process for producing a protective layer on a base material, comprising:
arranging a nanofilm directly on the base material and a brazing metal on the nanofilm, forming the protective layer comprising the brazing metal by locally igniting the nanofilm to start an exothermic reaction in the nanofilm that heats and fuses the brazing metal onto the base material, wherein the nanofilm forms nanofilm hard materials during the exothermic reaction, the method further comprising: arranging the nanofilm and the brazing metal in such a manner that nanofilm hard materials which remain after the exothermic reaction are arranged in the manner of roof tiles or in the manner of fish scales, and arranging a plurality of nanofilms with a plurality of brazing metals one on to of another before the exothermic reaction. |
