Surface integrity and flexural strength improvement in grinding partially stabilized zirconia



Zirconia has been used in medical applications since last few years and an optimum and cost-effective condition in grinding zirconia has drawn industrial attention. This paper aimed to improve and control the surface integrity, flexural strength and grinding cost in grinding partially stabilized zirconia (PSZ) using a diamond grinding wheel. The phase transition and grindability of PSZ were also evaluated. Ground surfaces analysis shows that all samples subjected to the grinding presented an increase in surface integrity, and the subsurface damages 100 below the surface were reduced from 3.4% to 0.9%. The flexural strength using 3 point bending test (3PB) shows that grinding increased the flexural strength more than 29% which is the result of higher surface integrity. The ground surfaces were analyzed using X-ray diffraction (XRD) and the results shows that T-M phase transition trend is in accordance with the surface integrity. In other words, XRD analyses prove that T-M phase transition results in higher flexural strength and surface integrity. It was also observed that in the best condition, the grinding cost was reduced by 72%. It can be concluded that controlling the grinding condition in grinding PSZ will result in the increase of the surface integrity and flexural strength. A mathematical model was created to find an optimum condition using response surface method (RSM). It is observed that feed rate has greater effect on the outputs rather than depth of cut.


近年来氧化锆一直被应用于医学领域,如何获得优化、低成本的氧化锆磨削条件引起了工业界 的关注。本文使用金刚石砂轮磨削部分稳定氧化锆(PSZ),以提高和控制其表面完整性、弯曲强度和 磨削成本,并研究PSZ 的相变和可研磨性。通过表面分析发现,所有经过磨削的样品表面完整性都有 所增加,表面下100 μm 的表面损伤从3.4%降到了0.9%。弯曲强度试验表明,弯曲强度提高了29% 以上,这是由于磨削获得了较高的表面完整性。用进行X RD 表面分析发现,T-M 相变趋势与表面完 整性一致,即T-M 相变可以提高弯曲强度和表面完整性。而且在最佳条件下,磨削成本降低了72%。 因此,控制磨削PSZ 中的磨削条件可以改善表面完整性和弯曲强度。利用响应表面法(RSM)建立数学 模型来获得最优条件,发现进给量对输出的影响大于切削深度。
