Abstract
A process is provided for producing coated synthetic bodies during which, before the coating, the surface to be coated is subjected to a pretreatment in an excited gas atmosphere. The surface is then coated. The gas atmosphere is predominantly formed of a noble gas and nitrogen and/or hydrogen, and the ionic energy in the gas atmosphere and in the are of the surface to be coated is not more than 50 eV. The ionic energy is selected to be not more than 20 eV, preferable not more than 10 eV. The gas atmosphere is excited by means of a plasma discharge or by means of UV radiation.
