“…Such identification of Ti 2 (Cu,Ni) was also obtained by Qin and Feng in brazing CFC/TC4 using Cu and Mo interlayers . The EDS result of microzone W indicates that the light‐gray area in the filler layer corresponds to Ti(Cu,Ni), which is in agreement with the result obtained by Liu et al…”

Joining of graphite to Ti6Al4V (TC4) alloy is achieved with three Cu-based fillers (Cu-22TiH 2 , Cu-50TiH 2 , and Cu-30TiH 2 -5Ni). Microstructural characterizations reveal that a thin TiC layer and a diffusion layer containing Ti solid solution (Ti(ss)) with Ti 2 Cu are developed at the graphite/filler layer and filler layer/TC4 interfaces, respectively. For the joint obtained with Cu-22TiH 2 filler, the filler layer consists of TiCu and Ti 2 Cu, whereas it is composed of Ti 2 Cu, TiCu, and Ti(ss) for the joint with Cu-50TiH 2 filler. In the case of the joint with Cu-30TiH 2 -5Ni filler, the filler layer mainly contains Ti(Cu,Ni) and Ti 2 (Cu,Ni). The microhardness of the interfacial area in the joints is highly related to the microstructure of joints. The filler layer of the joint with Cu-50TiH 2 filler exhibits higher microhardness than those with Cu-22TiH 2 and Cu-30TiH 2 -5Ni fillers, owing to the high content of Ti 2 Cu phase with relatively high microhardness and the increase in hardness of Ti-Cu intermetallics at higher brazing temperatures. The high shear strength of joints reveals favorable bonding of Cu-based fillers with substrates.

“…TiB whisker formation has an effective influence on the strengthening of the joints. Other authors [39] achieved better results on the brazing of Ti6Al4V to ZrB2-SiC ceramic using TiCu-based amorphous filler. The brazing temperature used was 910 °C , with a dwell time ranging from 10 to 50 min under 1.4 kPa of contact pressure.…”

The prospect of joining titanium alloys to advanced ceramics and producing components with extraordinary and unique properties can expand the range of potential applications. This is extremely attractive in components for the automotive and aerospace industries where combining high temperature resistance, wear resistance and thermal stability with low density materials, good flowability and high oxidation resistance is likely. Therefore, a combination of distinct properties and characteristics that would not be possible through conventional production routes is expected. Due to the differences between the coefficients of thermal expansion (CTE) and Young's modulus of metals and ceramics, the most appropriate methods for such dissimilar bonding are brazing, diffusion bonding, and transient liquid phase (TLP) bonding. For the joining of titanium alloys to ceramics, brazing appears to be the most promising and cost-effective process although diffusion bonding and TLP bonding have clear advantages in the production of reliable joints. However, several challenges must be overcome to successfully produce these dissimilar joints. In this context, the purpose of this review is to point out the same challenges and the most recent advances that have been investigated to produce reliable titanium alloys and ceramic joints. for next-generation aircraft turbine engines [1][2][3][4]. Though, the development of bonding techniques especially to successfully produce dissimilar joints is the key to overcoming the poor room-temperature ductility and fracture toughness of these alloys that limit these potential applications.The possibility of combining the extraordinary properties of these titanium alloys with other materials such as nickel-based superalloys, steel, or even ceramics through dissimilar bonding can allow the development of components not only with complex geometries but also with a combination of properties exceeding the limitations of these materials when used individually.Advanced ceramics have attractive properties, such as high wear resistance, high thermal stability as well as high thermal and electrical conductivities. It is known that some of the advanced ceramics like alumina, silicon nitride, and zirconia, are also well established in the electronics, aerospace, nuclear, and automotive industries [19,20]. However, their inherent brittleness, high cost, and high hardness limit the production of large and complex shape components. The successful application of these advanced ceramics depends strongly on the joining of these materials with metals. In addition, the possibility to combine properties as high wear resistance and high thermal stability with low density, high temperature properties, and excellent creep and corrosion resistance could enable the production of more advanced components that better meet the high requirements of several industrial sectors [21].The most suitable methods for bonding metals and ceramics and producing successful joints with appreciated properties are brazing , diffusion bonding...
