Abstract: The invention relates to etchants for etching surfaces, in particular metal surfaces. The etchants are characterised in that they can be removed without residue from the respective etched surface.

Abstract: In a process according to the invention and an apparatus according to the invention for the coating or modification of a surface a flow of a first gaseous phase or of a first aerosol comprising one or more precursor compounds is guided along a heated filament so that the precursor compounds are converted into reactive compounds. Alternatively, non-activated particles are guided along a heated filament so that these are activated and are then combined with a gaseous phase or an aerosol comprising a plurality of precursor compounds, so that the precursor compounds are thereby converted into reactive compounds. The reactive compounds formed according to at least one of the two aforementioned steps are guided onto a substrate that is exposed to atmospheric pressure, so that a layer is deposited on the substrate or its surface is modified.
