“…The mechanism of diffusion bonding in this study is similar to that of pressure sintering (Figure 8), where the material at the surface yields plastically and the surface asperities are deformed [26,27]. Material transfer is believed to occur through two stages: surface diffusion that begins from a single source at the surface to a neck and volume diffusion that begins from surface sources to necks.…”

Diffusion bonding is a process that has proven effective for the joining of metal to ceramic, but the differences in coefficient of thermal expansion still pose challenges during and after the bonding process. This work details the exploration of traditional diffusion-bonding processes using two traditional approaches, which include bonding of a 99.9+% pure Ni foil to SiC, Si3N4, and YSZ disks using (1) a hot isostatic press (HIP), with and without added weight to promote interfacial contact, and (2) field-assisted sintering (FAST). Samples were consolidated by heating to 1200 °C and held for 6 h under vacuum before cooling to room temperature during the HIP method. For the FAST technique, bonding experiments were performed at both 800 °C and 1200 °C in a vacuum environment under 10 MPa uniaxial pressure. After the Ni was bonded to the ceramics, diffusion heat treatments were carried out in the HIP. For electroless-plated samples, the heat-treatment temperature was chosen as 825 °C to avoid melting. For electroplated samples, heat treatment occurred at 925 °C or higher. Electroplated YSZ samples were heat-treated at 1150 °C as the Ni-Si eutectic is not a concern in this system. The time at temperature varied from 6 h to 48 h depending on the material combination tested. Post-heat-treatment diffusion characteristics were analyzed using scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDS). A main cause of poor bonding performance in the HIP samples was reduced interfacial contact, while cohesive failures in the FAST samples are likely due to the formation of brittle intermetallic Ni-Si phases. Preliminary results indicate success in bonding Ni to SiC, Si3N4, and YSZ using a diffusion-enhanced approach on electroplated specimens.

“…The second stage includes the diffusion and power-law-creep processes. Additional recrystallization and grain growth may also occur during the bonding process due to long exposures in a high-temperature environment [26,27]. Further study is needed to confirm the proposed bonding mechanisms.…”

“…From these preliminary experiments, cracks, distortions, and discoloration were shown and bonding did not occur between SUS316L and zirconia at the interface as shown in Figure . Although difference of CTE was reduced by using materials that have similar CTE, the result demonstrated difficulty in bonding because of the different crystallographic and thermal properties . In order to improve the bonding, the mixed layer was used.…”

The joint part of stainless steel 316L (SUS316L)/zirconia was investigated. The specimens were fabricated using the powder injection molding (PIM) with insert‐injection molding. SUS316L, zirconia, and a mixture of SUS316L and zirconia were used as bonding materials. The processing conditions for PIM were developed and optimized to avoid defects in the final sintered part. The bonded parts of SUS316L/mixed layer and zirconia/mixed layer were fabricated without joint failure. However, warpage and contamination existed due to the different sintering behavior and remaining binders. To reduce the warpage, the solids loading of SUS316L were changed to 44 and 40 vol. %. The warpage was decreased by reducing the shrinkage difference between the SUS316L and mixed layer. The contamination was also reduced by increasing the powder bedding in the debinding and sintering process. The microstructures and chemical compositions were confirmed by a scanning electron microscope (SEM) and an energy dispersive X‐ray spectroscope (EDS). Migration of the main components was observed at the interface and the main components were presented together at the whole part interface and interface between 2 materials in the mixed layer. It was confirmed that the joining was done with bonding of the same materials in each layer and diffusion bonding.

“…The diffusion bonding occurs only when minimum and essential energy of bonding overcomes the initial energy barrier of atoms. Lemus-Ruiz et al (2011) explained the mechanism of diffusion bonding. Contemporary adhesion of close proximity between two regions of nearer surfaces produces interfacial joining.…”

This chapter is intended to present the basic concept of roll bonding (RB) and accumulative roll bonding (ARB) of light-weight ductile metals. For this purpose, a discussion on previous research works on RB and ARB has been incorporated in this chapter. The general mechanisms of joining after rolling and several applications of RB and ARB have also been discussed. In the present study, an investigation on influence of various parameters on joint strength was conducted. Preheat temperature and percentages of thickness reduction are found to influence joint strength in a significant manner. The influence of annealing temperature and annealing time on mechanical properties of roll-bonded products in terms of controlling parameters has also been discussed here. The significant influence of preheat temperature and corresponding thickness reduction on the bond strength has been thoroughly discussed with a mechanism of peel testing. An attempt has been made to establish the mechanism behind failure along the joining line during peel testing of bond strength of solid-state welding through rolling.
