“…Moreover, the cross-section of the vacuum brazing coating (figure 3 At the cladding temperature, the liquid NiCrBSi filler metal was wetted and spread between the coating and the substrate to form an interface. Simultaneously, certain amount of liquid NiCrBSi filler metal prevented the WC particles from converging in the interlayer direction owing to the diffusion of the remelting elements, thus forming the interface [23]. The WC particles could not be contained in the surface layer of coating (filler metal layer) because they had not reached the decomposition temperature in liquid NiCrBSi filler metal aggregated in the direction of the interface under the action of gravity.…”

This study prepared a WC-10Ni/NiCrBSi composite coating on Q235 steel employing flexible coating cloth and vacuum brazing technologies. The surface hardness and corrosion resistance of the coating were characterised by the Vickers hardness, electrochemical, and micro-electrochemical tests. The results show that the corrosion resistance of the coating improved with the increase in cladding temperature. Moreover, with the increase in WC-10Ni content, the corrosion resistance of the coating decreased. Through transmission electron microscopy, scanning electron microscopy, and energy dispersive spectroscopy analysis, it is shown that there is galvanic corrosion in the micro-zone corrosion, where the WC particles are protected as cathodes, and the hardness of the coating is not affected by electrochemical behaviour. Thus, the hardness of the coating is not affected when it is applied in a corrosive environment.

“…The mechanical characteristics and corrosion resistance of Fe-W-B alloys in particular are severely limited by the large contents of intermetallic borides generated due to phase transitions during the continuous cooling of the liquid phase, such as Fe 7 W 6 and Fe x B, etc. [ 12 , 13 ]. The powder metallurgy technique provides several benefits over the conventional casting method, including lower production costs and a more environmentally friendly process [ 14 , 15 ].…”

High-quality Fe-Cr-Ni-W-B spherical powder is crucial for the powder metallurgy preparation of high-strength and tough Fe-Cr-Ni-W-B alloys. In this study, the controlled preparation of high-quality Fe-Cr-Ni-W-B spherical powder was achieved using the vacuum gas atomization method. The effects and mechanisms of atomization gas pressure, the melt nozzle inner diameter, and heat treatment temperature on the microstructure and flowability of Fe-Cr-Ni-W-B spherical powder were systematically investigated. By optimizing process parameters, spherical Fe-Cr-Ni-W-B powder with a sphericity of 95.1% and a flowability of 15.88 s/50 g was obtained, laying the foundation for the powder metallurgy preparation of high-strength and tough Fe-Cr-Ni-W-B alloys.
