Method for cold gas spraying |
| 摘要 |
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 m2/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. |

1. A method for cold gas spraying, in which a spray powder containing photocatalytically active spray particles is accelerated in a nozzle by means of a carrier gas and forms a coating upon impact with a substrate, characterized in that at least a part of the photocatalytically active spray particles consists of nanocrystalline agglomerates that have a porosity from 200 to 800 m2/g, wherein the porosity is determined by a BET measurement using nitrogen and the nanocrystalline agglomerates have been sintered to a hardness of between 0.1 and 4 GPa, wherein the hardness is measured with a nanoindenter. |
