In this study, the galvanic corrosion behavior of the side surface of titaniumclad steel plate (TCSP) and below the defects, which penetrate through the titanium layer of TCSP, have been focused on. Electrochemical corrosion tests and infinite focus three-dimensional measurement results revealed that galvanic corrosion on the side of TCSP will lead to widespread pitting of the steel, and the distribution positions of pits in splash, tidal, and submerged zones are different. Severe corrosion occurs below the defects in the titanium layer of TCSP, and the larger the defect, the deeper the corrosion depth, but TCSP with smaller defects have larger corrosion width on the Ti-Stl line (the joint between the titanium and steel). This shows that the size of the defect will influence the density of corrosion products and the effect of TCSP defect internal corrosion on titanium layer peeling is extremely limited.

“…The brittle products such as oxides and nitrides at the interface of titanium clad steel can be effectively inhibited and the interface bonding strength can be improved. In addition, vacuum rollcladding can produce wide and thick plates, which has broad application prospects [14][15][16]. Though oxides and nitrides at the interface can be effectively inhibited during vacuum roll-cladding, TiC and Ti-Fe metal brittle compounds are easily formed at the interface of Ti and steel during the process of heating, rolling and cooling, which reduce the interfacial bonding property of Ti steel clad plate [17][18][19].…”

The titanium clad steel plates were prepared by vacuum roll-cladding (VRC) in three ways: without interlayer, with Fe interlayer and Ni interlayer. With the increase in temperature, the TiC layer becomes thicker and the metal compounds increase at the interface during VRC without interlayer. The bonding strength is 266 MPa at 900°C. The Fe interlayer effectively inhibits the diffusion of C element and reduces the amount of TiC. The fracture is brittle and partial ductile, and the interface bonding strength improved. The Ni interlayer can prevent the interdiffusion of Ti and Fe elements, but brittle TiC and Ti-Ni compounds are formed at the interface. The bonding strength is low, and the fracture is brittle, which occurs at the Ti-Ni interface.

“…To improve the practical applicability of Ti-steel sheet (SS) bonded joints, it is necessary to increase their plasticity by reducing the volume fraction of intermetallic compounds (IMCs) using some form of solid state connection method, or selecting a suitable interlayer material for the Ti alloy and stainless steel so as to form a solid solution between them during the bonding process. The use of hot-roll diffusion bonding to form dissimilar joints has attracted signi cant attention in the recent literature [17][18][19]. Hot-roll bonding provides an effective means of joining similar or dissimilar materials without gross microscopic distortion or large dimensional tolerances [20,21].…”

“…Finally, the bonding time is very short, and thus the volume fraction of IMCs formed at the bonding interface is greatly reduced. Many studies have shown that the inclusion of an aluminum (Al) [24][25][26], copper (Cu) [28,29], nickel (Ni) [22], or silver (Ag) [23] interlayer increases the strength of hot-roll diffusion-bonded Fe-Ti joints [17][18][19]30] and suppresses the formation of IMCs [29][30][31][32][33][34]. However, even though a small improvement in the bonding strength is achieved, the bonding strength at the joints is still limited by the formation of brittle IMCs at either the Ti/interlayer or the interlayer/SS interface.…”

This study performed experiments and thermodynamic calculations to elucidate the effects of diffusion temperature on interfacial evolution and mechanical properties of pure titanium and carbon steel (i.e., steel) sheets bonded via a new type of multi-pass continuous hot-roll diffusion with nickel interlayer. The interfacial evolution results revealed that this new type of multi-pass continuous hot-roll diffusion treatment showed a very good adherence due to its metallurgy bonding, because it made a remarked improve to between compound and intermetallic compounds relationship. Secondly, in mechanical properties results revealed that the highest shear strength (∼470 MPa) was obtained at a processing temperature of 850°C. The highest peel strength (∼21 N/mm) was obtained in the sample processed at 900°C. Bonding temperatures above and below these levels reduced the bond strength respectively due to poor atom diffusion and excessive compound formation, resulting in joint failure at the Ti-Ni interface. Extensive cleavage planes with various alignments were observed on the fracture surfaces in these cases. Overall, a hot-rolling temperature of 850°C was found to provide the optimal tradeoff between interfacial bonding strength and ductility. This work provided an economical and convenient solution for broadening the engineering application of interface between sheets of pure titanium and steel.
