项目摘要

In this study, the (Ti,V)N coated cemented carbide tools that have several contents of Ti and V are used. The experimental conditions for deposition of (Ti,V)N films are an arc current of 100A, a substrates DC bias of 100V, a substrate temperature of 673K and a N_2 gas pressure of 2.7Pa. The substrate used is Cemented carbide (JIS K10). The cathode materials used are Ti75V25, Ti50V50 and Ti25V75. In order to clarify the effective tool material for the turning of various workpieces, the tool wear of the (Ti,V)N coated cemented carbide tool is experimentally investigated. The main results obtained are as follows: (1) The TiN coating layer has the micro-hardness of HV_<0.25N>1940 and the critical scratch load of 64N, The Ti75V25N coating layer has the micro-hardness of HV_<0.25N>2970 and the critical scratch load of 90N. The Ti50V50N coating layer has the micro-hardness of HV_<0.25N>2820 and the critical scratch load of 80N. The Ti25V75N coating layer has the micro-hardness of HV_<0.25N>2510 and the critical scratch load of 91N. Therefore, the Ti75V25N coated cemented carbide has both high micro-hardness and high critical scratch load. (2) The Ti75V25N coated cemented carbide tool is the most effective tool material for the cutting of SUS310S. (3) In the cutting of sintered iron material, the wear progress of Ti75V25N coated cemented carbide tool is slowest in the PVD coated cemented carbide tools. (4) The Ti75V25N coated cemented is the most effective tool material for the cutting of the sintered stainless steel. (5) In the cutting of forged sintered material, the wear progress of Ti75V25N coated cemented carbide tool is slowest in the PVD coated cemented carbide tools.

在本研究中，使用了具有多种Ti和V含量的（Ti，V）N涂层硬质合金刀具。沉积（Ti，V）N薄膜的实验条件为：电弧电流100A，衬底直流偏置100V，衬底温度673K，氮气压力2.7Pa。基材为硬质合金（JIS K10）。正极材料为Ti75V25、Ti50V50、Ti25V75。为了明确车削各种工件的有效刀具材料，对（Ti，V）N涂层硬质合金刀具的刀具磨损进行了实验研究。得到的主要结果如下：(1)TiN涂层的显微硬度HV_<0.25N>1940，临界划痕载荷为64N； Ti75V25N涂层的显微硬度HV_<0.25N>2970，临界划痕载荷为90N。Ti50V50N涂层的显微硬度HV_<0.25N>2820，临界划痕载荷为80N。Ti25V75N涂层显微硬度HV_<0.25N>2510，临界划痕载荷91N。因此，Ti75V25N涂层硬质合金具有较高的显微硬度和较高的临界划伤载荷。(2) Ti75V25N涂层硬质合金刀具是切削SUS310S最有效的刀具材料。(3)在切削烧结铁材料时，Ti75V25N涂层硬质合金刀具的磨损进程在PVD涂层硬质合金刀具中是最慢的。(4) Ti75V25N涂层硬质合金是切削烧结不锈钢最有效的刀具材料。(5)在切削锻造烧结材料时，Ti75V25N涂层硬质合金刀具的磨损进程在PVD涂层硬质合金刀具中是最慢的。
