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.

在这项研究中，使用（Ti，v）n涂层的粘贴碳化物工具，具有Ti和V的多个含量。（Ti，V）N膜沉积的实验条件是100a的电弧电流，100V的底物DC偏置，底物温度为673K，N_2气压为2.7Pa。所使用的底物是碳化物（JIS K10）。使用的阴极材料是TI75V25，TI50V50和TI25V75。为了阐明有效的工具材料用于转动各种工件，（Ti，v）n涂层胶结碳化物工具的工具磨损得到了实验研究。所获得的主要结果如下：（1）TIN涂层层具有HV_ <0.25N> 1940的微硬度，临界刮擦负载为64N，TI75V25N涂层具有HV_ <0.25n> 2970和90N的关键刮擦负载的微硬度。 Ti50v50n涂料层具有HV_ <0.25N> 2820的微硬度和80N的临界划痕载荷。 Ti25v75n涂料层具有HV_ <0.25N> 2510的微硬度，而临界刮擦负荷为91N。因此，Ti75v25n涂层的碳化物具有很高的微度和高关键的刮擦负荷。（2）TI75V25N涂层碳化物工具是切割SUS310的最有效的工具材料。（3）在切割烧结的铁材料时，Ti75v25n涂层碳化物工具的磨损进度最慢。（4）Ti75v25n涂层胶结是切割烧结不锈钢的最有效的工具材料。（5）在切割锻造的材料时，Ti75v25n涂层碳化物工具的磨损进度在PVD涂层的胶结碳化物工具中最慢。
