Microstructural study of Ti/3YSZ interface in NI 105/Ni/Nb/Ti/3YSZ diffusion bonding
In this research, the diffusion bonding of the stabilized zirconia ceramic and Nimonic 105 superalloy using Ti/Nb/Ni multi-interlayer was carried out. Joint was performed using the plasma spark technique in a vacuum atmosphere and at different temperatures and times. The microstructure of the different joint zones was studied using optical and FESEM microscopes equipped with an EDS analyzer. Th...

متن کاملInvestigation of diffusion bonding quality by ultrasonic technique
For high-temperature ultrasonic transducers piezoelement-to-metal thermosonic bonding technology was developed based on goldto-gold diffusion. Bond quality strongly depends on bonding parameters – pressure, temperature, ultrasonic power and time. The first step for achieving good bonds was ultrasonic monitoring of the process. In ultrasonic transducers good diffusion bond means good acoustic co...
متن کاملDiffusion bonding of hardmetals (WC-Co) with metallic interlayers
Diffusion bonding of hardmetals (WC-Co) to themselves or with other metallic material (mildsteel) has been evaluated in the present paper. Metallographic studies and mechanical tests have been used to determinate the influence of the bonding parameters (temperature, pressure and time) on the bond microstructure and strength. Different metallic interlayers applied in form of thick foils were use...
متن کاملEffect of diffusion bonding temperature on microstructure properties of Zr/Ti interlayer in the diffusion bonded joints of Zr702 to A516 steel
In this study, the effect of temperature on the microstructure and reactive layer at the interface between the Ti interlayer and the base metal related to the diffusion bonding of Zr702 to A516 low alloy steel was investigated. The joining was done using the spark plasma sintering technique at temperatures of 900, 950 and 1000°C for 30 minutes. Field Emission Scanning Electron Microscope (FESEM...
