چکیده مقاله
In this research, the diffusion bonding of the stabilized zirconia ceramic and Nimonic 105 superalloy with Ti/Nb/Ni multi interlayer was carried out using the spark plasma sintering technique The microstructure of the different joint zones was studied using field emission electron microscopes equipped with an EDS analyzer The results showed that the critical region is Ti/3YSZ interface and in all conditions diffusion bonding in Ti/Nb, Nb/Ni and Ni/NI 105 interfaces were done Microstructural observations showed that in the Ti/3YSZ interface at all temperature and time conditions, the connection of two separate regions was formed due to the difference in the diffusion depth of Ti, Zr and O elements and with increasing temperature and time, the thickness of these regionsincreased Microstructural studies showed that the best connection was performed at a temperature of 900℃ and a time of 30 minutes Microhardness bservations and EDS analyzes confirmed that Ti3O reaction layer is the weakest zine
