According to the nanoindentation hardness, critical scratch load, and friction coefficient, the multilayer VN/AlCrN-coated films have mechanical and tribological properties to comparable to those of the TiN, AlCrN, and VN films. Owing to the formation of Magneli-phase oxides, the friction coefficient decreased as the temperature increased above approximately 500deg. The cutting forces of the VN-rich VN/AlCrN-coated tools were lower than those of TiN and AlCrN-rich tools, which were mainly caused by the tribological effect of the lubricious VN film. Meanwhile, the flank wear width of the multilayer VN/AlCrN-coated tools were relatively small due to the higher harness of the VN film. In addition, the cutting temperature of the VN/AlCrN-coated tools were considerably lower than that of the VN-coated tool, indicating a synergetic effect for wear resistant AlCrN and self-lubricating VN coating materials., 研究課題/領域番号:18H01349, 研究期間(年度):2018-04-01 - 2021-03-31, 出典:「窒化バナジウムを含有する高温潤滑複合コーティング膜の開発とその難削材加工への適用」研究成果報告書 課題番号18H01349 (KAKEN:科学研究費助成事業データベース(国立情報学研究所)) (https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-18H01349/18H01349seika/)を加工して作成}, title = {窒化バナジウムを含有する高温潤滑複合コーティング膜の開発とその難削材加工への適用}, year = {2021} }
