摘要

Tool, especially a cutting tool comprises a substrate member onto which at least one layer is deposited by means of chemical vapor deposition (CVD), and a method for CVD of a two-phase layer on a sintered part. The individual deposited layers or at least one of them contain TiCN-, TiOCN-, TiOC-, or TiC phases and an additional ZrO 2 and/or HfO 2 phase. An independent claim is included for CVD of a two-phase layer in a gas atmosphere containing TiCl 4, HfCl 4 and/or ZrCl 4 and CO 2, acetonitrile, pyridine, or benzene, remainder hydrogen and/or argon.
