Figure 3

Variations of (a) Young’s modulus E and (b) hardness H as a function of depth z below the G/Z/G surface. G/Z/G specimens were fabricated from presintered Y-TZP plates (1400°C for 1 hr) followed by glass infiltration at 1450°C for 2 hrs. Three distinctive zones are apparent: an outer surface residual glass layer (I), a graded glass-zirconia layer (II), and a dense Y-TZP interior (III).
