Abstract: A doctor beam for use in a printing unit, e.g. a flexographic printing unit, wherein the doctor beam has a front side with a U-shaped channel, wherein the doctor beam is made of metal and includes a surface coating produced by Plasma Electrolytic Oxidation (PEO), the surface coating at least covering the U-shaped channel, and wherein the doctor beam further includes a non-stick ceramic coating, whereby is achieved the possibility of using metal for making doctor beams without risking their degrading, neither due to chemical impact of the applied inks/lacquers/primers nor due to the destruction of the surface coating by cleaning liquids. The invention also concerns a method for treating the surface of a doctor beam and use of a doctor beam.

Abstract translation: 用于印刷单元的刮刀光束，例如。 柔性版印刷单元，其中所述刮刀梁具有具有U形通道的前侧，其中所述刮刀梁由金属制成并且包括由等离子体电解氧化（PEO）产生的表面涂层，所述表面涂层至少覆盖所述U 并且其中刮刀梁还包括不粘陶瓷涂层，由此实现了使用金属制造刮刀梁的可能性，而不会由于所施加的墨水/喷漆/底漆的化学冲击而引起其降解的风险， 通过清洗液体破坏表面涂层。 本发明还涉及一种用于处理刮刀梁的表面和使用刮刀梁的方法。
