“…To overcome this drawback, the self-joining of ceramics or connection to metals has been proposed. Up to date, joining ceramics and metals can be realized through brazing [3,4], diffusion bonding [5,6], and transient liquid phase bonding [7,8]. However, unwanted residual stresses at joint interfaces turn out during the cooling processes because of poor wettability of ceramics and mismatches of coefficients of thermal expansion (CTE) between ceramics and metals.…”

In order to relieve high residual stresses between ceramics and metals during brazing processes, an AgCuTi/graphene-reinforced Cu foam composite filler was developed and used to braze the ZrB2-SiC ceramic and Inconel 600 alloy.Microstructures and shear strengths of the joints were systematically studied. The joints are composed of TiFe2, TiCu, TiC, Cu(s, s), Ag(s, s), and Ti5Si3 phases. It is found the addition of graphene on the Cu foam surface can effectively retard diffusions of metal atoms and avoid the collapse of the foam matrix. After being brazed at 900 o C, the joint can get a maximum shear strength of 157 MPa, much higher than those brazed without graphene addition. The high shear strength was investigated in detail and attributed to the integrity of the Cu foam, formation of the TiC and thickness of the reaction layer at the ceramic side.

“…The nano-Si 3 N 4 particles were introduced into the AgCu powder filler, where the growth of continuous Ti-Cu intermetallic layers adjacent to TC4 alloy was suppressed [10]. Valenza et al systematically studied the weldability and wetting of the ZrB 2 /ZrB 2 , ZrB 2 /TC4 and ZS/TC4 using Ag-, Cu-and Ni-based filler [11][12][13]. The mechanism of joint formations was revealed.…”

In this work, the Ti-6Al-4V alloy and ZrB 2 -SiC ultra-high temperature ceramic joint was brazed by TiCuZrNi amorphous filler at 910℃ with varied holding time. The element diffusion, microstructure and precipitation phase of the joints were analyzed in details. Reaction products in the joints were identified as β-Ti, (Ti,Zr) 2 (Cu,Ni), TiCu, Ti 2 Cu, TiC, Ti 5 Si 3 , TiB and TiB 2. The formation schemes of reaction products were investigated. The holding time has substantial impacts on interfacial microstructure and shear strength of joints. A maximum shear strength of 345 MPa of the joint was reached under a brazing temperature of 910℃ and holding time of 1200 s. It is also found that the shear strength depends on the amount of eutectic structure and brittle compounds in the joints.

In other work by the same authors [37] it was evaluated the brazing of Ti6Al4V to ZrB 2 and ZrB 2 -SiC using a Ni-based interlayer. The interlayer was prepared by the mixture of B-Ni 50 at% powder.…”

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...
