Abstract

A method and an apparatus for coating substrates is described in which the layer to be applied is produced by the condensing particles of a plasma generated by a gas discharge which are incident on the substrates. Both an arc discharge vaporization coating process and a cathode sputtering coating process are effected in the same apparatus, and the arc discharge vaporization process is carried out before the cathode sputtering process.
