Special Issue Information

Dear Colleagues,

Recent advancements in welding, spraying, surface cladding, and related material-joining technologies have enhanced the integrity and performance of assembled components, leading to the development of advanced manufacturing methods. Although advanced technologies have been developed for several decades now, significant and exciting innovations often arise from both the process and/or material side, providing an opportunity to solve many engineering problems.

Another key area of interest is related to the corrosion and oxidation of metal joining for welding, spraying, and surface cladding. The microstructural changes induced by welding, spraying, and surface cladding techniques can drastically modify the metal’s mechanical behavior. For that reason, it is necessary to correlate the corrosion and oxidation behavior of process parameters, microstructure, and mechanical responses in welding, spraying, and surface cladding. Finally, the simulation and modeling of the thermomechanical behavior during the processing for corrosion and oxidation resistance and the predictions of existing phases due to the thermal cycle are critical to optimizing processing (e.g., welding, spraying, surface cladding, and joining) parameters.

For this Special Issue, papers related to advanced welding, spraying, and surface cladding in metal joining for corrosion and oxidation behavior for various material spraying, surface cladding, 3D printing, laser welding, friction stir welding, electron beam welding, arc welding, and hybrid welding are welcome. Papers that combine both experimental and theoretical approaches are especially welcomed.

Contributions from around the world will add to the success of this Special Issue, which aims to spread the potential of advanced welding, spraying, and surface cladding in metal joining well-established and innovative metallic parts.

The isothermal steam oxidation behavior of the Zr−Sn−Nb alloy at 1050 °C was studied. In this study, the oxidation weight gain of Zr−Sn−Nb samples with oxidation durations ranging from 100 s to 5000 s was calculated. The oxidation kinetic properties of the Zr−Sn−Nb alloy were obtained. The macroscopic morphology of the alloy was directly observed and compared. The microscopic surface morphology, cross-section morphology, and element content of the Zr−Sn−Nb alloy were analyzed using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and energy disperse spectroscopy (EDS). According to the results, the cross-sectional structure of the Zr−Sn−Nb alloy consisted of ZrO2, α-Zr(O), and prior-β. During the oxidation process, its weight gain versus oxidation time curve followed a parabolic law. The thickness of the oxide layer increases. Micropores and cracks gradually appear on the oxide film. Similarly, the thicknesses of ZrO2 and α-Zr versus oxidation time were in accordance with the parabolic law. Full article

The solar electroflotation (EF) processes using saline electrolytes are today one of the great challenges for the development of electrochemical devices, due to the corrosion problems that are generated during the operation by being in permanent contact with Cl ions. This manuscript discloses the corrosion behavior of titanium electrodes using a superposition model based on mixed potential theory and the evaluation of the superficial performance of the Ti electrodes operated to 4 V/SHE solar electroflotation in contact with a solution of 0.5 M NaCl. Additionally provided is an electrochemical analysis of Ti electrodes regarding HER, ORR, OER, and CER that occur during the solar saline EF process. The non-linear superposition model by mixed potential theory gives electrochemical and corrosion parameters that complement the information published in scientific journals, the corrosion current density and corrosion potential in these conditions is 0.069 A/m2 and −7.27 mV, respectively. The formation of TiO2 and TiOCl on the anode electrode was visualized, resulting in a reduction of its weight loss of the anode electrode. Full article
