Pressure cylinder (1) comprises a surface coating (2) made from either a pure nickel layer, a mixed crystal alloy, composite layers or multiple layer systems for engraving a stepped ensemble (3). The multiple layer system contains copper or nickel as main components. An Independent claim is also included for a process for the production of a surface coating of a pressure cylinder.
