在WC-6wt%Co硬质合金刀片上沉积了离子镀PVD TiN、TiCN和高离子溅射PVD TiAlN涂层。对涂层和基体的显微组织和力学性能进行了表征。涂层刀具在低、高切削速度下车削Inconel 718、中碳钢SAE 1045和球墨铸铁时进行了评价。TiAlN涂层刀具表现出最好的金属切削性能，其次是TiCN和TiN涂层刀具。TiAlN涂层刀具的上级性能（在更高的速度下甚至更高）与涂层对磨料和凹坑磨损的更高抗性有关。这些特性是由于TiAlN在加工操作过程中通常在工具尖端遇到的温度下具有较高的热硬度和抗氧化性。(C)1999由Elsevier Science Ltd.出版。保留所有权利。
Ion-plated PVD TiN, TiCN, and high-ionization sputtered PVD TiAlN coatings were deposited on WC-6wt%Co hardmetal inserts. Microstructural and mechanical properties of the coatings and substrate were characterized. Coated tools were evaluated in turning of Inconel 718, medium cal bon SAE 1045 steel, and ductile iron at low and high cutting speeds. TiAlN coated tools showed the best metalcutting performance, followed by the TiCN and TiN coated tools. The superior performance of the TiAlN coated tools, which was even greater at higher speeds, is related to the coating's higher resistance to abrasive and crater wear. These characteristics are a result of the higher hot hardness and oxidation resistance of TiAlN at the temperatures normally encountered at the tool tip during machining operations.
