Hybrid coating for tooling authors: • Tibor Cselle - Andreas Lümkemann, PLATIT AG, Selzach Switzerland • Mojmir Jilek, PLATIT a.s., Sumperk, Czech Republic Abstract: Today, the ARC and sputtering processes dominate the PVD coating market. By combining muliple processes t during a deposition process, a hybrid layer is created to combine the benefits of the different methods. For most larger tools (larger than Ø 2  mm), the drop lets can be removed through polishing. There are several methods available for this[1], such as: brushing, micro blasting (dry and wet), drag finishing and stream grinding....

processes The hybrid layer BorAC® (AlCrTiN/BN) was simultane ously deposited from three ARC cathodes and one sput tering cathode, increasing the sputtering power in steps (figure 2). By reducing the grain size from 57  nm to 16  nm, the hardness increases with decreasing residual stress of the layer. It is not self-evident, on the contrary, it is surprising and amazing. First practical results with hybrid layers produced by LACS® technology speed hobbing requires both high hardness and high toughness. This is the area for which the hybrid boron layer is already recognized as the best solution...

figure 6: The options of the hybrid coating unit Pi411 The SCIL® option offers significant benefits when incor porated into the LACS® option and benefits from the high ionization rate of the LGD of the ARC cathodes (without droplet formation). This increases the performance of con ventional sputtering layers, such as TiB2, WC / C. References [1] Compendium, 61st edition PLATIT AG, Selzach, 2019 The LACS® option can also be used to make conventional coatings such as AlCrN. Good adhesion is guaranteed by the LGD®. The smooth layers are produced by the simul taneous SCIL® cathode with high ionization...
