氮化硼系复合涂层、具有该复合涂层的梯度超细硬质合金刀具及其制备方法
Abstract:
一种氮化硼系复合涂层、具有氮化硼系复合涂层的梯度超细硬质合金刀具及其制备方法。氮化硼系复合涂层由TiBCN层、Ni3Si2层和CBN层构成。合金刀具由刀具基体和氮化硼系复合涂层构成。刀具基体设置有正常组织层、富钴过渡层和贫钴富立方相层。复合涂层通过电弧离子镀设备沉积而成。本发明的氮化硼系复合涂层，其与刀具基体结合性良好，复合涂层的涂层之间附着力良好，耐高温性、耐腐蚀性、耐磨性良好。具有该氮化硼系复合涂层的梯度超细硬质合金刀具，具有良好的耐磨耐温性能。
Abstract(English):

A boron nitride composite coating comprising of a TiBCN layer, a Ni3Si2 layer, and a CBN layer, and a graded structure ultrafine hard alloy cutting tool with the coating. The cutting tool comprises a cutting tool base body and the boron nitride composite coating. The cutting tool base body is provided with a normal organization layer, a cobalt-rich transition layer, and a cobalt-poor cube-rich phase layer. The composite coating is deposited by an arc ion plating device. The boron nitride composite coating has good adhesion to the cutting tool base body, good layer-to-layer adhesion within the composite coating, and good resistance against high temperatures, corrosion, and abrasion. The graded structure ultrafine hard alloy cutting tool with the coating has excellent abrasion resistance and heat resistance.
