采用非平衡磁控溅射离子镀方法,对高速钢刀具表面进行了涂层沉积处理,研究了表面涂层的显微形貌、物相组成和涂层的摩擦磨损性能,并对比分析了无涂层和有涂层刀具的切削性能。结果表明,高速钢表面的涂层组织致密、均匀,实现了与基体的良好冶金结合;不同偏压下涂层的物相均为Cr、Cr_2N、Cr N和Fe_3Mo_3N;高速钢刀具表面涂层在使用温度为600℃以下时具有较高的抗热摩擦磨损性能,而在温度为600℃以上时抗热摩擦磨损性能相对较差;高速钢刀具表面进行的非平衡磁控溅射离子镀沉积处理涂层,可以对切削刃起到良好的保护作用,并可以抑制或者减少刀具的磨损。
The unbalanced magnetron sputter ion plating method was used to coat and treat the surface of HSS tool. The microstructure, phase composition and friction and wear properties of the coating were studied. Coated and coated tools cutting performance. The results show that the coating on the HSS surface is dense and uniform, and the metallurgical bond with the substrate is achieved. The phases of the coatings under different bias voltages are Cr, Cr_2N, CrN and Fe_3Mo_3N. When the temperature is below 600 ℃, it has a higher resistance to thermal friction and wear, while the thermal friction and wear resistance is relatively poor when the temperature is above 600 ℃. The unbalanced magnetron sputter ion plating deposition The coating protects the cutting edge and inhibits or reduces tool wear.
