“…Nanoparticles of metals have advantage for metal-metal bonding [8][9][10][11][12]. Metal-metal bonding is typically implemented by applying both pressure and temperature to the materials to be bonded, which promotes diffusion of metals into the materials [13][14][15]. A decrease in a size of material to nanometer order provides a depression of its melting point [16,17].…”

The present study performs production of copper oxide particles, and examines the particles as a filler in metalmetal bonding. Leaf-like aggregates with a longitudinal size of ca. 600-950 nm and a lateral size of ca. 280-380 nm, which were composed of particles with a size of ca. 10 nm, were produced with a salt-base reaction using a Cu(NO3)2 aqueous solution and an NaOH aqueous solution. Copper discs were bonded by pressurizing them, between which the particles were sandwiched, at 1.2 MPa for 5 min in H2 gas under annealing at 400 • C. Bonding properties of particles were evaluated by measuring shear strength, which was required to separate the discs. The shear strengths were as large as ca. 23 MPa at NaOH/Cu(NO3)2 ratios of 1.9 and 2.0, since CuO particles that contained nether Cu2(OH)3NO3 nor impurity based on the addition of NaOH were produced at the ratios.

“…Cottenden et al [86] investigated the metallurgical structure and strength of dissimilar joints of cemented carbide and copper, cobalt, and nickel. Diffusion-bonded joints exhibit superior mechanical properties compared with those of brazed joints [87]. These results lay a foundation for revealing the mechanism of η-phase formation.…”

Cemented carbides have been widely used in aerospace, biomedical/wearable sensor, automobile, microelectronic, and other manufacturing industries owing to their superior physical and chemical properties at elevated temperatures. These superior properties, however, make it difficult to process these materials using conventional manufacturing methods. In this article, an overview of the welding and joining processes of cemented carbide and steel is given, followed by a few examples of welding processes. Cemented carbides can be successfully joined by sinter-bonding, brazing and soldering, laser beam welding, tungsten inert gas (TIG) welding, diffusion welding, friction welding, electron-beam welding, and chemical vapor deposition. An overview of the benefits and drawbacks of brazing and soldering of cemented carbide and steel is presented, including reports on joint design, processes, and selection of brazing filler metals. The laser welding of cemented carbide and steel is addressed and reviewed, including reports on gap bridging ability, the inclusion/absence of filler metals, interlayers, and laser/TIG hybrid welding. Finally, a section is devoted to explaining the main issues remaining in the welding and joining of cemented carbide, corresponding solutions, and future work required.

“…Under vibration and impact, cemented carbide composites have low toughness due to the inherent brittle nature of carbides [11][12][13]. Joining of WC-Co to structural steel is a dissimilar material joining problem [14], involving various joining techniques, including brazing [15][16][17], diffusion bonding [18][19][20], fusion welding [21][22][23][24], and partial transient liquid-phase bonding [25]. Among the joining techniques, brazing is a commonly used technique for joining cemented carbides to steels, because of its simple processing and relatively low cost.…”

Surface mining causes significant wear damage that affects equipment performance, reliability, and lead to associated downtime costs. To improve the wear resistance of components used in natural resources industries, cemented carbide tiles are joined to engaging surfaces of the components. Joining of cemented carbide to structural steel can be achieved by various processes, among which brazing is commonly used owing to its relatively simple processing and low cost. A significant challenge in brazing cemented carbide tiles to steels is the poor joint strength. This article aims to review the recent progress in improving joint strength of cemented carbide/steel brazing. Recent progress on the key factors, including type of filler metals, evolution of joint microstructure, generation of residual stresses, and process parameters have been closely examined and critically analysed. Future directions of research on brazing cemented carbide tiles to steel in order to improve joint strength have been proposed.
