The invention relates to a method for galvano-plastic production of a nozzle with an inner surface area whose gradient can be constructed to be variable with respect to an axis of symmetry and in particular to run in the opposite direction, an electrolytic metal deposition being applied as a positive form of the nozzle body on a basic element of the negative form of the nozzle body and subsequently the basic element being dissolved/detached in a chemical or mechanical fashion, and to the use of a nozzle produced in this way. The galvano-plastic production of nozzles with complicated inner wall surfaces is known from DE-C 2828993. The object on which the invention is based consists in utilising the abovementioned method in such a way that nozzles with complicated geometries and extremely small dimensions can be manufactured in a cost-effective and a reproducible fashion. The solution is characterised in that the surface of the positive form of the nozzle body, in particular in its inner surface is provided by means of a wear-resistant layer.
