Abstract

本发明涉及一种表面涂覆有抗冲击耐磨涂层的CBN刀片，属于机械和超硬工具技术领域，刀片的CBN层上涂覆有抗冲击耐磨涂层，CBN层上涂覆有至少一层的抗冲击耐磨涂层，抗冲击耐磨涂层的材料为TiN、TiC、Ti(C,N)、(Al，Cr)N，抗冲击耐磨涂层的厚度范围在0.8‑8微米时为薄膜涂层，抗冲击耐磨涂层的厚度范围在8‑20微米时为厚膜涂层，本发明的益处为可用于淬硬钢、轴承钢、高速钢、冷硬铸铁的粗车和精车，高温合金、热喷涂材料、硬质合金及其他难加工材料的高速切削加工，比无涂层刀具能容忍更高的切削速度，且具有更长的使用寿命，因此可以大大提高加工效率、降低加工成本。

Description

一种表面涂覆有抗冲击耐磨涂层的CBN刀片
技术领域
本发明涉及一种表面涂覆有抗冲击耐磨涂层的CBN刀片，属于机械和超硬工具技术领域。
背景技术
立方氮化硼(CBN)是氮化硼的同素异构体，其结构与金刚石相似，硬度高达8000～9000HV，耐热度达1400℃，但对于淬硬钢(45~65HRC)、轴承钢(60~64HRC)、高速钢(63~66HRC)、冷硬铸铁的粗车和精车，高温合金、热喷涂材料、硬质合金及其他难加工材料进行高速切削加工会使刀片加速磨损，刀片寿命变短，降低了工作效率，增加加工成本。
发明内容
为了克服现有技术结构的不足,本发明提供一种表面涂覆有抗冲击耐磨涂层的CBN刀片。
本发明解决其技术问题所采用的技术方案是：刀片的CBN层上涂覆有抗冲击耐磨涂层。
刀片的CBN层下还包含合金层。
CBN层上涂覆有至少一层的抗冲击耐磨涂层。
抗冲击耐磨涂层的材料为TiN、TiC、Ti(C,N)、(Al，Cr)N。
多层抗冲击耐磨涂层采用PVD技术沉积所产生的涂层和CVD技术沉积所产生的涂层。
抗冲击耐磨涂层的厚度范围在0.8-8微米时为薄膜涂层。
抗冲击耐磨涂层的厚度范围在8-20微米时为厚膜涂层。
多层抗冲击耐磨涂层按粒度分为纳米涂层和微米涂层。
本发明的益处为可用于淬硬钢、轴承钢、高速钢、冷硬铸铁的粗车和精车，高温合金、热喷涂材料、硬质合金及其他难加工材料的高速切削加工，比无涂层刀具能容忍更高的切削速度，且具有更长的使用寿命，因此可以大大提高加工效率、降低加工成本。
附图说明
