    摘要:

    采用真空阴极电弧离子镀技术,在TC11钛合金和单晶Si片表面分别沉积不同调制周期、不同RTi/TiN:RZr/ZrN调制比和不同厚度的Ti-TiN-Zr-ZrN多层膜。用扫描电镜、X射线衍射仪、划痕仪、显微硬度计和应力测试仪分析测试了多层膜的截面形貌、厚度、结合力、硬度和残余应力;重点研究了调制周期、调制比和膜层厚度等调制结构的改变对多层膜残余应力和相关性能的影响。结果表明:增加调制周期,则残余应力降低,结合力和硬度均增大;降低RTi/TiN:RZr/ZrN调制比,则残余应力增大,结合力下降,硬度增加;增大多层膜厚度,则残余应力略有上升,结合力和硬度都提高,当膜层厚度达到7.54μm后,硬度稳定在30Gpa左右。

    Abstract:

    Ti-TiN-Zr-ZrN multilayer films were deposited on TC11 titanium alloy and Si wafer by vacuum cathodic arc ion plating technology. The Ti-TiN-Zr-ZrN multilayer films with different modulation periods, different RTi/TiN:RZr/ZrNmodulation ratio and different thickness. The structure and performance of the multilayer films, especially residual stress were investigated by various analytical methods including scanning electron microscopy (SEM), X-ray diffraction(XRD), micro-hardness tester, scratch adhesion tester and stress gauge. The results show that increasing the modulation period, residual stress decreased, adhesive strength and hardness were increased. Reduce the modulation of RTi/TiN:RZr/ZrN modulation ratio, is residual stress and hardness increases, the adhesive strength decreased. Increasing the thickness of multilayer films, residual stress increased slightly, adhesion and hardness are improved. the film’s hardness around at 30Gpa when it’s thickness up to 7.54μm.
