涂层硬质合金刀具磨损速率和它的性能变化都很小,所以刀具耐用度可提高2—4倍。为了搞清刀具磨损减小的原因,进一步制订出涂层硬质合金刀具在各种加工方案下的磨钝标准,用涂层和无涂层Bκ6、T15κ6、T30κ4、TT10κ8Б、κHT-16方形(12.7×12.7×4.75毫米,r=0.8毫米)可转位式硬质合金刀片进行了试验。对比试验采用瑞典Sandvik Coromant公司生产的GC型硬质合金刀片,对用热扩散饱和法(ДT)和气相沉积法(ГT)所得到的TiC涂层,用真空离子轰击等离子沉
Coated carbide tool wear rate and its performance changes are small, so the tool durability can be increased 2-4 times. In order to find out the reasons for the decrease of tool wear, the blunt standard of coated carbide cutting tools under various processing schemes was further developed. The coated and uncoated BK6, T15K6, T30K4, TT10K8B, and κHT-16 square 12.7 × 12.7 × 4.75 mm, r = 0.8 mm) indexable cemented carbide inserts were tested. The comparative tests were performed on a GC-type cemented carbide insert manufactured by Sandvik Coromant Co., Sweden. The TiC coating obtained by the thermal diffusion-saturation method (ДT) and the vapor deposition method (ΓT) was subjected to vacuum ion bombardment
