项目摘要

Ti-W-C-N system coating films formed by PVD method, which are new type coating films, have been developed in this research. In order to clarify the effective tool material for the turning of various workpieces, the tool wear of the Ti-W-C-N system coated cemented carbide tools are experimentally investigated. The substrate used is cemented carbide JIS K10. The cathode material used is TiW.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 (Ti,W)N coating layer, which is the bias voltage -150V, has the micro-hardness of HV_<0.25N>1970 and the critical scratch load of 148N.2.In the cutting of SCr420H, the Ti-W-C-N coated cemented carbides are the effective tool materials. In the Ti-W-C-N coated cemented carbide tools, the wear progress of the (Ti,W)N coated cemented carbide tool, which is the bias voltage -150V, is slowest.3.In the cutting of SUS304 or SUS310S, the wear progress of the (Ti,W)N coated cemented carbide tool, which is the bias voltage -300V, is slowest.4.In the cutting of sintered steel, there was little difference between the wear progress of the (Ti,W)N coating film and the (Ti,Al)N coating film.5.In the cutting of sintered stainless steel, the (Ti,W)C coated cemented carbide tool is the most effective tool material in the (Ti,W)(C,N) coated cemented carbides.

这项研究已开发出由PVD方法形成的Ti-W-C-N系统涂料膜，即新型涂料膜。为了阐明有效的工具材料，可以研究Ti-W-C-N系统涂层碳化物工具的工具磨损。所使用的底物是胶结的碳化物JIS K10。所使用的阴极材料是TIW。获得的主要结果如下：1。锡涂层具有HV_ <0.25N> 1940的微硬度，而关键的刮擦负荷为64N。（Ti，w）n涂层层是偏置电压-150V，其微硬度为HV_ <0.25N> 1970，临界刮擦负荷为148n.2.在切割SCR420H时，Ti-W-C-N涂层的胶质碳水化合物是有效的工具材料。在Ti-W-C-N涂层的碳化物碳化物工具中，（Ti，w）N涂层的碳化物胶带工具的磨损进度（即偏置电压-150V）的磨损最慢。3。在切割SUS304或SUS310中，（Ti，w）N涂层的碳化物固定的固定液的磨损进展，是sin的cotials-ias-300 cutias-ias by iias。钢，（ti，w）涂层膜的磨损进度与（Ti，al）N涂层膜之间几乎没有差异。5。切割烧结的不锈钢，（Ti，W）C涂层碳化物工具是（Ti，w）（c，n）涂层胶质胶质的碳化物中最有效的工具材料。
