本文利用直流三极偏压溅射法在刀具上沉积了碳化钛膜，用球坑仪测量了膜厚，并用ＨＸ－１０００显微硬度计测量了膜的维氏硬度：实际试验表明，刀具的使用寿命提高了３～５倍。
In this paper, a direct current three-pole bias sputtering method was used to deposit a titanium carbide film on the tool. The film thickness was measured by a ball-pits instrument. The Vickers hardness of the film was measured by a HX-1000 micro hardness tester. Life increased by 3 to 5 times.
