Abstract: Disclosed is a process for forming a coating on a substrate (2,2') by cate sputtering, comprising the coating of substrate surfaces (2,2') which have been transferred to a cathode sputtering chamber (1). The substrates vary in width and have a predetermined maximum width. The process involves the use of a target (3) whose surface (4) has an invariable length corresponding approximately to said maximum substrate width. A shift takes place, in accordance with the width of the substrate being coated, between the surface (4) of the target and the substrate surface to be coated, so that the entire surface of the target remains more or less constantly in front of the surface to be coated during the cathode sputtering process.

Abstract: A film of a composite material is deposited by electropolymerization onto electrically conductive surface. A mixture comprising a monomer, a substance forming a dopant, a supporting electrolyte and a solvent is subjected to electrolysis in which the conductive surface to be coated is used as either cathode or anode. The cathode or anode is polarized to a potential between the electron transfer between the electrically conductive surface and the monomer. Prior to electrolysis, a solution is made from the mixture containing the substance forming a dopant either as anion, cation, molecule, and/or as undissociated complex.
