长石质和氟磷灰石饰瓷在模拟咀嚼循环条件下耐磨性能的研究
|
摘要
目的:比较模拟咀嚼循环条件下长石质饰瓷与氟磷灰石饰瓷的耐磨性能。方法:制备2种饰瓷长条形试件各10个,用于物理性能测试和表面形貌观察;另制备圆盘形试件各6个,分别在水环境、加载力10 N、转速200 r/min的条件下进行120万次循环磨损实验;于每10万次循环节点测量各饰瓷的体积磨损量和表面粗糙度;然后分别在磨损10、70、120万次循环节点观察各饰瓷磨损面的微观形貌,分析磨损区域的基本组成及其所占比例。结果:两种饰瓷的体积磨损量、表面粗糙度曲线均呈现正相关近似线性上升趋势,在每个测量节点,氟磷灰石瓷的体积磨损量、表面粗糙度均明显高于长石质瓷(P<0.05);长石质瓷表面均匀一致,而氟磷灰石瓷表面有较多大小不一且散在分布的气孔;随着加载循环的进行,两种饰瓷的磨痕均由稀疏变为密集,磨损面上均可见磨屑粘着。结论:在模拟咀嚼循环条件下,氟磷灰石瓷的耐磨性能较长石质瓷差。
AIM: To compare the wear resistance of feldspathic porcelain( FEP) and fluorapatite porcelain( FLP) in simulated oral environment. METHODS: 10 rectangular samples of each group were subjected to wear test by means of three point bending method and the indentation method,the surface structure was observed by SEM after acid corrosion. 6 disc shaped samples in each group were subjected to wear test by a wear machine under water lubrication condition at the speed of 200 r / min and loading force of 10 N. The wear volume and roughness were measured by the three-dimensional profiler scanner per 105 cycles. Surface morphology were observed by SEM after 105,7 × 105,and 12 × 105 cycles respectively. EDX energy analysis was used to measure the basic composition and the proportion of the wear area. RESULTS: The volume loss,surface roughness of the two porcelains increased linearly with the wear process. The volume loss and surface roughness of FLP were higher than that of FEP at each measurement cycle. SEM images showed that there were many different sizes of pores on FLP surface. With the cyclic loading,the wear scar of the two materials became from sparse to dense. FLP was worn in the form of relatively small particles and relatively dense grooves. FEP was worn in the form of relatively big particles and relatively sparse grooves. There were visible particles adhered to the wear area. CONCLUSION: The wear resistance of fluorapatite porcelain is lower than that of feldspathic porcelain.
