Summary
This study showed that yttria stabilized zirconia can be brazed to 444 stainless steel by in-situ alloying of pure Ni-Ti foils at temperatures around 1000°C.The best brazes were produced when brazing for 60 minutes at 1010°C and 30 minutes at 1030°C.Four different regions were identified across the braze metal which were influenced by the interactions of the Ni/Ti alloy with the metal and ceramic substrates.Significant interactions occurred between the Ni/Ti braze metal and the stainless steel.Cr and Fe were found to diffuse into the braze metal,but did not reach a narrow braze metal band near the YSZ.There was little interaction between the braze metal and the YSZ,but a strong bonding was produced at this interface.It is speculated that the bonding occurred due to the localized reduction of ZrO2 and oxidation of Ti that formed a solid solution.
