Claim:
Process for the coating or modification of a surface, including the following steps: a) providing a first gaseous phase or a first aerosol, comprising one or more precursor compounds that can be converted into one or more reactive compounds by heating on a filament; b) converting said one or more precursor compound(s) into one or more reactive compound(s) by guiding a flow of the first gaseous phase or of the first aerosol along a first heated filament disposed in a flow hollow body; and c) leading the one or more reactive compound(s) formed according to step b) onto a substrate that is disposed outside of the flow hollow body and exposed to atmospheric pressure, to form a layer on or to modify a substrate surface; wherein the overall particle stream density in the flow after formation of the one or more reactive compound(s) is >10 mole/(m 2 s).
