The modelled residual stress distribution in Zirconia and reaction layer by image based modelling, (a) the in plane residual stress in zirconia of the joint with a rumpled interface, (b) the out of plane residual stress in zirconia of the joint with a rumpled interface, (c) the in plane residual stress in zirconia of the joint with a flat interface, (d) the out of plane residual stress in zirconia of the joint with a flat interface, (e) the in plane residual stress in the reaction layer of the joint with a rumpled interface, (f) the out of plane residual stress in the reaction layer of the joint with a rumpled interface, (g) the in plane residual stress in the reaction layer of the joint with a flat interface, (h) the out of plane residual stress in the reaction layer of the joint with a flat interface. (i) The in plane residual stress distribution as a function of depth in zirconia with a rumpled interface and flat interface, (j) the residual stress distribution along the path drawn in figure (f,h). The hardness distribution in the interface region of (k) a surface micromachined YSZ/Ti6Al4V joint, regions with relatively low hardness can be found adjacent to the grooves in the YSZ substrate, (l) a flat YSZ/Ti6Al4V joint, the measured hardness value is decreasing from the interface to the surface of the YSZ, (m) The averaged hardness distribution as a function of depth in a surface micromachined YSZ/Ti6Al4V joint and a flat YSZ/Ti6Al4V joint, a “jump” feature can be observed in the surface micromachined YSZ/Ti6Al4V joint hardness trend.
