Description

一种SmN-WSe2软硬复合涂层刀具
技术领域
本发明涉及一种SmN-WSe2软硬复合涂层刀具，属于刀具涂层材料技术领域。
背景技术
机械制造业为整个国民经济提供技术装备，是国民经济和社会发展以及国防建设的物质基础，其发展水平是国家综合实力的重要标志。切削加工技术是机械制造业中应用最广泛的基础技术，而切削刀具技术的进步则是切削加工技术快速发展的关键。近年来，为满足干切削、高速切削等对切削刀具提出的新的要求，金属切削工具行业在不断尝试开发新型耐磨刀具材料、刀具涂层以及开展刀具几何结构的优化设计，这些方法均在一定程度上解决了限制切削技术发展的瓶颈问题。在这些方法中，其中以涂层的适用性最为广泛，但涂层与基体材料之间的结合问题成为了制约其性能发挥的一大因素，尤其是涂层与刀具基体结合部分的过渡层的结合性能至关重要；其次，软硬复合涂层中的软涂层具有润滑功效，但往往软涂层的寿命有限。为此，开发新型的高结合强度的涂层刀具、强化软涂层的寿命设计对促进涂层刀具应用范围的扩大以及切削加工技术的进步将具有重要意义。
中国专利“申请号：201710532821.3”报道了AlNbCN多元梯度复合涂层刀具及其制备方法，该发明通过采用中频磁控溅射和多弧镀的复合方法在刀具基体表面依次沉积Ti过渡层、AlNbC过渡层、含氮量梯度渐变的AlNbCN涂层，该刀具具备较高的硬度和强度，可应用于多种金属材料的精加工和半精加工。中国专利“申请号：201710532824.7”报道了SiZrCN梯度复合涂层刀具及其制备方法，该发明采用非平衡磁控溅射和电弧镀的复合镀膜方法在刀具基体表面沉积氮含量梯度渐变的SiZrCN梯度硬涂层，其中以Ti作为过渡层，该涂层具备良好的硬度和热稳定性。
发明内容
技术问题：
本发明的目的在于克服现有技术的不足，提供一种SmN-WSe2软硬复合涂层刀具，提高涂层与基体之间的界面结合强度，提升软涂层的服役寿命。
技术方案：
本发明的一种SmN-WSe2软硬复合涂层刀具，刀具的基体材料为硬质合金、陶瓷等硬脆材料，涂层沿基体材料向外依次为Sm过渡层、SmN硬涂层、WSe2软涂层，Sm过渡层的厚度为0.4～0.6μm，SmN硬涂层的厚度为1.5～2.0μm，WSe2软涂层的厚度为1.0～1.5μm；SmN硬涂层的外表层分布有规则的微米尺度的织构，单元织构的尺寸在0.5～1.0μm，织构采用电子束加工技术成形以保证尺寸精度，WSe2软涂层部分沉积在织构内部。
有益效果：
相比现有的硬涂层材料，本发明的SmN硬涂层具有相对较高的硬度，具有更好的耐磨性；Sm过渡层因其特有的原子结构特性而具有很好的致密性，使得硬涂层与基体之间能够保持良好的结合特性。相比现有的软涂层，本发明的规则的微米尺度织构设计能够存储和承载软涂层，使得软涂层的服役寿命提高。本发明可广泛应用于金属材料的干式切削加工，涂层具有耐磨和润滑的突出优势，可有效改善干式切削的工况，提高材料加工的综合生产效率。
