钛电弧离子镀膜结合强度的实验研究

Experimental study on the bonding strength between FCVA film and titanium

目的:研究钛表面电弧离子镀膜的结合强度。方法:以德国工程师手册(VDI3198)为标准,通过压入实验测量膜结合强度,利用扫描电镜观察膜结构及其与基体的结合情况。结果:载荷为400N时,膜的断裂模式属于HF3;扫描电镜可见膜与基体结合良好、厚度均匀、平整,膜厚度约为1.2μm。结论:钛表面电弧离子镀膜与基材间的结合强度能够满足临床需要。

PURPOSE： To study the bonding strength between the FCVA（filtered cathode vacuum arc） film and the titanium substrate.METHODS： According to the Engineer Manual of Germany（VDI3198）,the indentation test was applied to evaluate the bonding strength between the FCVA film and the titanium substrate.The structure of the FCVA film and the interface between the film and the substrate were observed by means of scanning electron microscope（SEM）.RESULTS： The fracture pattern of the film was classified as HF3 at the load of 400N,the bonding strength was enough between the FCVA film and the titanium substrate.SEM photograph showed the thickness of the FCVA film was about 1.2μm equably and the film bonded to the substrate well.CONCLSION： The bonding strength between the FCVA film and the titanium substrate was enough to meet clinical demand.
