Abstract
The invention relates to a method for producing at least one functional region on an electrical contact element such as, for example, a switching contact or a plug type contact. In order to prevent the high environmental burden which is disadvantageous in wet-chemical methods and to overcome the restriction to a very small number of materials caused in hot dip methods in physical technical terms, and to substantially improve the spatial possibility for selection and structuring which is insufficient in both techniques, there is provision according to the invention for at least one material coating to be applied mechanically in a highly selective manner to the contact element in the functional region and subsequently highly energetic thermal radiation such as, for example, a particle beam in the form of an ion and/or electron beam, to be directed onto the at least on material coating.
