“…In the Ag-Cu-Ti/SiC brazing system, the emergence of TiC layers precedes the Ti 5 Si 3 layer at the tip by investigating the nanoscale dynamic wetting and spreading of molten Ti alloy on 6H-SiC by Shun-Ichiro Tanaka et al and the detailed reaction mechanism analysis was in Section 3.3 and Figure7A and B 29.

A two-step process involving, the pre-metallization of the SiC ceramic by Ag-Cu-Ti foil and the Al based filler alloy was developed to join 2219 aluminum alloy and the metallized SiC. The composition of metallized SiC layer was investigated. The effect of metallization temperature on the microstructure and mechanical properties of the joint was analyzed. The brazing process showed that Al from the brazing filler and 2219 substrate reacted with Ag-Cu-Ti alloy to form intermetallic compounds. Al 3 Ti, Al 2 Ag and Al 2 Cu were detected in the joint. Ti 5 Si 3 , TiC and Ti 3 SiC 2 compounds were found adjacent to the reaction layer of the Ti and SiC. With increasing of metallization temperature, the shear strength of joint first increased and then decreased. The joint shear strength reached 16.0 MPa when the pre-metallization temperature reached 1000 • C and holding time was 10 min.

Icephobicity of materials has received intensive attention in recent years due to the increasing requirement of ice protection in aerospace, wind energy and power lines. However, the influencing factors of material icephobicity have not been well identified. In this work, the effect of surface gaseous adsorption on icing behaviour of materials was investigated for the first time.Ni-Cu-P coatings with different surface morphologies were fabricated and used as the objects of the study. Environmental scanning electron microscopy (ESEM) was utilized to observe the water condensation and ice formation on the coatings. X-ray photoelectron spectroscopy (XPS) was employed to analyse the variations of surface adsorption. Droplets icing time and ice adhesion strength of the coatings were also studied. The results showed that the icing time of water droplets on the Ni-Cu-P coatings increased significantly, and the ice adhesion strength decreased sharply with the spontaneous surface adsorption of gaseous species (mainly hydrocarbon groups) in air. The adsorbed hydrocarbon species would promote the formation of air pockets between the ice-coating interface, which could effectively reduce the interfacial contact of the formed ice with the coating. When the adsorbed hydrocarbon species were removed by plasma cleaning, water droplets tended to have more direct contacts with the coatings prior to icing, leading to the formation of interlocked ice and significantly increased the ice adhesion on the surface. The variation of surface icephobicity can also be attributed to the changes of surface energy due to the surface adsorption. The results indicated that the surface gaseous adsorption in air played an important role in determining the surface icing behaviour and the icephobicity of the materials.

“…In addition, high joining temperatures inevitably lead to a large residual thermal stress in the ceramic-metal joints because of the high coefficient of thermal expansion (CTE) mismatch, which deteriorates the joint strength. 12 TLP bonding involves the formation of a liquid phase through the melting of interlayers or interfacial reactions and the isothermal solidification of the liquid by atomic interdiffusion; the joining temperature is lower compared with that in diffusion bonding, but the resultant joints show great potential for high-temperature applications. 13 However, the joining time for TLP bonding is typically several to tens of hours, which severely limits the use of this technique.…”

A direct current (DC)‐driven transient liquid phase bonding strategy was proposed for joining 3 mol% Y2O3‐stabilized ZrO2 (3YSZ) and GH3128 superalloy with a Ni interlayer. The DC application triggered the rapid formation and diffusion of metallic Zr in 3YSZ and chemical reactions at the 3YSZ/Ni interface. The formed Ni–Zr eutectic liquid well wetted 3YSZ and hence completely filled the bonding gap in seconds. Eutectic structures in the joints were eventually transformed into Ni–Zr intermetallic compounds or a Ni‐based solid solution. The remaining Ni interlayer effectively alleviated residual stress through plastic deformation during cooling stage, and thereby contributed substantially to the high joint strength. Under the joining conditions of a current density of 30 mA/mm2, an energization time of 30 s, and a joining temperature of 1100°C, the obtained joints exhibited a maximum shear strength of 188 ± 8 MPa. This paper proposes an economical and reliable method for the rapid preparation of YSZ/metal joints for high‐temperature applications.
