复合涂层骨钻用钻头、其制备方法及骨钻
摘要：
本发明是关于复合涂层骨钻用钻头、其制备方法及骨钻。本发明一实施例提供一复合涂层骨钻用钻头，其包括：骨钻用钻头；骨钻用钻头的表面依次附着渗氮层、物理气相沉积PVD涂层和抗菌纳米粒子改性的PVD涂层，其中PVD涂层为包括AlCrN、CrAlN、CrN、TiN、AlTiN、TiAlN、TiAlCrN、TiSiN、TiSiAlN、TiAlWN或其混合物的纳米硬质涂层。本发明实施例提供了复合涂层骨钻用钻头、其制备方法及骨钻，其通过在骨钻用钻头的表面依次沉积渗氮层、PVD涂层和抗菌纳米粒子改性的PVD涂层形成复合涂层骨钻用钻头，一方面增强了骨钻用钻头的硬度及耐磨性，另一方面，抗菌纳米粒子改性的PVD涂层中的抗菌纳米粒子也能有效抵抗细菌，降低患者感染细菌的风险。
摘要（英）：

The invention relates to a drill bit for a composite coating bone drill, a preparation method of the drill bit and the bone drill. One embodiment of the invention provides the drill bit for the composite coating bone drill; the drill bit comprises a drill bit body for the bone drill, wherein a nitriding layer, a PVD (Physical Vapor Deposition) coating and an antibacterial nanoparticle modified PVD coating are sequentially attached to the surface of the drill bit body for the bone drill; the PVD coating is a nano hard coating prepared from AlCrN, CrAlN, CrN, TiN, AlTiN, TiAlN, TiAlCrN, TiSiN, TiSiAlN, TiAlWN or a mixture of the elements. The .embodiment in the invention provides the drill bit for the composite coating bone drill, the preparation method of the drill bit and the bone drill; the nitriding layer, the PVD coating and the antibacterial nanoparticle modified PVD coating are sequentially deposited on the surface of the drill bit for the bone drill to form the drill bit for the composite coating bone drill; on the one hand, the hardness and wear resistance of the drill bit for the bone drill can be enhanced; on the other hand, bacteria can be effectively resisted by antibacterial nanoparticles in the antibacterial nanoparticle modified PVD coating, so that the risk of bacterial infection of patients is reduced.
