Abstract
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.
