Abstract (en)
Ink transfer roller (1) has a surface structure, mechanically applied or applied by laser, made of saucers (N) in a microporous, metallic or (metal)-ceramic hard material layer (HS). The novelty is that source microcracks (M) and pores are closed by ion implantation material (H) applied by high voltage plasma. The ion implantation material (H) is made of Ti and Mo, and is coated with a wear resistant thin layer covering layer (D) made of a hard material, esp. a metal oxide and/or metal nitride so that the covering layer has a predetermined affinity to the printing ink to be applied by the roller. The covering layer is made of ZrO2. The hard layer (HS) consists of polished Cr2O3 in a thickness of 100-150 mu m, or consists of plasma-deposited Ni-Cr alloy in a thickness of 100 mu m, or consists of steel, copper or nickel coated with metal matrix. The roller is produced by subjecting it to turbulent heavy metal implantation at 50-80 degrees C in a gas discharge plasma using a voltage of 1000 V. Ti and Mo ions are used in a wt. ratio of 70/30 to 90/10. ZrO2 is implanted from the gas discharge plasma.

Farbübertragungswalze mit einer mechanisch oder durch Laserung eingebrachten Oberflächenstruktur aus Farbübertragungsnäpfchen (N) in einer mikroporösen, metallischen oder keramischen oder metallkeramischen Hartstoffschicht (HS), wobei die oberflächlichen Mikrorisse (M) und Poren durch ein mit einem Hochspannungsplasma appliziertes metallisches Ionenimplantatmaterial (H) geschlossen sind. Eine Deckschicht (D) aus einem implantierten Oxid gibt eine erhöhte Glätte und eine gewünschte Öberflächenaffinität zur Druckfarbe. <IMAGE>
