摘要

目的是研究两种氧化钇-部分稳定氧化锆陶瓷的亚临界裂纹扩展现象，并测定其断裂韧性。两种材料中的一种是市售的5mol %氧化钇部分稳定氧化锆（5Y-PSZ），另一种是由3mol %和8mol %氧化钇稳定氧化锆粉（3Y+8Y-PSZ）的混合物制成的实验部分稳定氧化锆，最终样品采用立体光印（SLA）工艺制备。对水中试样进行不同应力速率下的三点弯曲试验，得到Weibull参数和SCG参数。结果表明：与5Y-PSZ （m = 8.57, σ0 = 647.25 MPa）相比，3Y+8Y-PSZ具有更高的威布尔模量（m = 11.54）和特征强度（σ0 = 812.27 MPa）；水中5Y-PSZ和3Y+8Y-PSZ的SCG参数n分别为26.03和37.94。5Y-PSZ和3Y+8Y-PSZ （Pf = 5%）经过10年的模拟使用，强度分别降低了56.49%和45.30%。对于两种材料的断裂韧性，无论采用何种方法测定，3Y+8Y-PSZ都具有更高的值。而维氏压痕法的拟合校正因子对5Y-PSZ和3Y+8Y-PSZ均不适用。恒应力率试验确定两种材料的SCG参数并预测其寿命是评价材料的有效方法。

Fracture toughness and subcritical crack growth analysis of high-translucent zirconia prepared by stereolithography-based additive manufacturing

The objective was to study the subcritical crack growth phenomena and determine the fracture toughness of two yttria-partially-stabilized zirconia ceramics. One of the two materials evaluated was a commercially available 5 mol% yttria partially stabilized zirconia (5Y-PSZ), and the other was an experimental partially stabilized zirconia made from a mixture of 3 mol% and 8 mol% yttria stabilized zirconia powder (3Y+8Y-PSZ), with the final samples prepared by the Stereolithography (SLA) process. The samples in water were tested by three-point bending experiments at different stress rates to obtain Weibull and SCG parameters. The results show that 3Y+8Y-PSZ has higher Weibull modulus(m = 11.54) and characteristic strength(σ₀ = 812.27 MPa) compared to 5Y-PSZ (m = 8.57, σ₀ = 647.25 MPa). SCG parameters n obtained for 5Y-PSZ and 3Y+8Y-PSZ tested in water were 26.03, 37.94, respectively. The strength of 5Y-PSZ and 3Y+8Y-PSZ (P_f = 5%) was reduced by 56.49%, 45.30% after 10 years of simulated use. Regarding the fracture toughness of both materials, 3Y+8Y-PSZ had higher values regardless of the method used to determine it. However, the fitting correction factor of the Vickers indentation method was not applicable to either 5Y-PSZ or 3Y+8Y-PSZ. Determining the SCG parameters of two materials and predicting their lifetimes using constant stress rate testing is an effective way to evaluate materials.

期刊介绍： The Journal of the Mechanical Behavior of Biomedical Materials is concerned with the mechanical deformation, damage and failure under applied forces, of biological material (at the tissue, cellular and molecular levels) and of biomaterials, i.e. those materials which are designed to mimic or replace biological materials. The primary focus of the journal is the synthesis of materials science, biology, and medical and dental science. Reports of fundamental scientific investigations are welcome, as are articles concerned with the practical application of materials in medical devices. Both experimental and theoretical work is of interest; theoretical papers will normally include comparison of predictions with experimental data, though we recognize that this may not always be appropriate. The journal also publishes technical notes concerned with emerging experimental or theoretical techniques, letters to the editor and, by invitation, review articles and papers describing existing techniques for the benefit of an interdisciplinary readership.
