Effects of chromium on the interface and bond strength of metal–ceramic joints

Interface formation and bond strength in 3Y-TZP/Cr composite bilayers produced by sinter–joining

“…This observation indicates that chromium has a tendency to interact with zirconia at high temperatures. Although this interaction has been reported by many others, for example [14][15][16], the mechanism of interface formation during sinter-joining has not been reported so far. To study this phenomenon, 3Y-TZP/Cr bilayers were sintered at a high temperature and the interface formation was studied through electron microscopy (SEM), electron probe microanalysis (EPMA), and micro-focused X-ray diffraction (MFXRD).…”

“…Earlier works [13,16] have shown that chromium segregate at the interface with oxide-ceramic materials to form an interface. Zhang et al [14] have shown Cr-aggregation during brazing of alumina to stainless steel by using a Cr-bearing Cu braze material. The interfacial reaction between chromium oxide and zirconia ceramic during diffusion bounding was reported by Qin and Derby [24].…”

An analysis of deformation mechanism in the Si3N4–AgCuTi+SiCp–Si3N4 joints by digital image correlation

“…This fracture type indicated a large thermal residual stress was resided in the joint, which was confirmed by previous researches. 27,28 Another type (Fig. 5(c)), for the case of the joint brazed with Ag-Cu-Ti + 5 vol.%SiCp composite filler, fracture altered between the Si 3 N 4 ceramic and brazing alloy.…”

Fabrication and micro-structure of a multilayer functionally graded (WC–Co)–Ni composite

“…Thus, the cemented carbide is considered as cutting, drilling and mining tool materials due to its high hardness and excellent wear resistance [1,2]. Considering the high cost and the hard machinability, these manufactured small cemented carbides products are usually joined with the steel substrate [3]. However, the differences in chemical and physical properties between cemented carbide and metal make it extremely difficult to get an excellent strength and toughness joint.…”
