“…The average fracture strength of brazed YSZ beams in this study was 36 MPa. This is in good agreement with the fracture strength of 20-30 MPa of fully stabilized zirconia blocks joined via Ti/Ag solder/Ti by Narita et al (9) The fracture strength of LPO-joined YSZ beam at 1273 K for 28.8 ks in this study was about four times greater than that for brazing techniques using Ag solder. and (c).…”

Liquid-phase oxidation (LPO) joining technique was employed to join yttria-stabilized zirconia (YSZ) blocks using Al/Fe-Cr alloy /Al interlayer for development of a gas sealing technique for solid oxide fuel cells (SOFCs). The YSZ blocks were joined at 1073 to 1473 K for 3.6 to 28.8 ks in vacuum (< 0.2 Pa) with a stress of 80 MPa and annealed at 973 K for 3.6 ks in air. The average four-point bend strength and Weibull modulus of LPO-joined YSZ specimen increased with increasing joining time at 1273 K. The specimen joined at 1273 K for 28.8 ks has a four-point bend strength of 135 MPa, which was about four times greater than that obtained by brazing technique using Ag solder, and comparable to unbonded monolithic YSZ. Polycrystalline alumina layer, which is expected to act as an insulating and protective layer, was formed between YSZ and Fe-Cr alloy after the LPO joining.

“…For example, fully stabilized zirconia ceramics joined using Ni alloy and Ag-Cu-Ti solder as interlayers had a weak fracture strength of 30 MPa, 11) and yttria-stabilized zirconia joined via Ni-NiO eutectic liquid had a joining strength of only 51 MPa by a shear test. 12) Joining techniques of heat resistant alloys to oxide ion conducting ceramics have also been studied, 11),13)-18) and strong joints were obtained by diffusion bonding of stainless steel to zirconia (720 MPa by four-point bend test) 16) and diffusion bonding of Ni alloy to zirconia (620 MPa by four-point bend test).…”

A joining technique for oxide ion conducting ceramics, such as yttria-stabilized zirconia, was developed, utilizing oxidation of transiently formed aluminum melt. Two yttria-stabilized zirconia (YSZ) blocks were joined via Al/Ni alloy/Al interlayers at 1273 to 1473 K for 3.6 to 28.8 ks in a vacuum (< 0.2 Pa) with an applied load of 80 MPa. The average fracture strength increased with increasing the joining time and temperature. A strong four-point bend strength of 170 MPa was obtained for the specimen joined at 1473 K for 14.4 ks, which was fractured at YSZ block. Alumina interlayer, which is expected to act as a protective layer for further oxidation of Ni alloy, was formed between YSZ and Ni alloy in the specimen after joining.
