Multifunctional multi-component PVD coatings for cutting tools

摘要

Highly wear resistant PVD coatings are well established in cutting operations. Further efforts to improve the cutting performance need to be focused on all relevant wear mechanisms. Thus, the objectives are an enhancement of the abrasive wear resistance, toughness, oxidation resistance, and reduction of friction. The aim of this work was to investigate properties and cutting performance of new multifunctional multicomponent PVD coatings based on Ti(1-x)A1(x)N applied to cutting tools. An industrial cathodic arc-evaporation unit was used to deposit coatings from powder metallurgically produced multi-component targets.
