Optical and SEM images of the fracture surface of 3Y-PSZ subjected to the biaxial flexural strength test after mouth-motion simulations at P = 200 N for various sliding cycles. (a), (e), (i), (m), and (q): optical microscope images of the fracture surface. The rest of the figures are SEM images of fractured surface at a consecutive series of magnifications, which illustrate the fracture origin and fracture origin flaws (indicated by arrows in Figs. d, h, l, p, and t).
