Analysis of modern research shows that the basis of binders is usually water, organic solvents or their mixtures in various proportions, and all three types are of almost equal importance depending on the specific application. Particular attention is paid to the rheological characteristics of binders, which determine the printability, as well as the binder removal process, which affects the phase composition of the resulting products. This review proposes a classification of binders for binder jetting, categorizing them into four types: liquid organic, solid, nanoparticle-filled, and reactive. Further development of binder jetting technology and expansion of its industrial application directly depend on research aimed at creating new binder systems that meet growing industrial requirements.

The proposed approach differs from traditional chemical methods in increased environmental friendliness due to combination of plasma treatment of the metal and the use of corrosion inhibitor (tannin) introduced into the liquid cathode. The experiments were performed on copper samples with corrosion damage, which served as a solid anode. The liquid cathode was an electrolyte consisting of aqueous solution of ammonium sulfate with concentration of 2%, supplemented with tannin (1 and 1.5%), prepared on the basis of technical grade water containing 0.02% calcium ions. In the presence of calcium ions, tannin forms a dense adhesive layer on the metal surface, helping to protect the surface from subsequent corrosion damage. During the study, the characteristics of electrical plasma discharges were measured, the dynamics of gravimetric parameters associated with corrosion damage were traced, and the microscopic condition and surface roughness were assessed using profilometry, which made it possible to identify optimal process parameters. Analysis of the results showed that plasma treatment with addition of tannin as a corrosion inhibitor improves the protective properties of the cleaned surface.

Plant extracts have become sustainable and environmentally benign substitutes for harmful synthetic inhibitors, providing a more environmentally favorable method of preventing corrosion. This study comprehensively investigated the corrosion inhibition potential of foxtail millet seed extract (FOE) on mild steel in 1 N HCl. The investigation employed a multi-faceted approach, including elemental analysis, preliminary screening, weight loss method at different temperature, kinetic, thermodynamic, adsorption studies. Surface characterization techniques such as scanning electron microscopy (SEM), and energy dispersive X-ray analysis (EDAX), and Fourier-transform infrared spectroscopy (FTIR) were utilized to confirm the presence of bioactive compounds and the extract’s adsorption on the metal surface. The inhibition efficiency (IE) of the FOE extract on mild steel increased with increasing extract concentration. Conversely, the IE decreased with rising temperature across the range of 303 to 343 K, indicating a temperature-dependent inhibition mechanism. A remarkable maximum inhibition efficiency of 96% was obtained for 3% v/v FOE at 303 K at 1 h. The adsorption process was found to adhere to multiple isotherm models, including Langmuir, Temkin, Freundlich, and El-Awady, with the Langmuir isotherm providing the optimal fit to the experimental data. Furthermore, activation parameters, namely activation energy (<i>E</i><sub>a</sub>), activation enthalpy (Δ<i>H</i>∗), and activation entropy (Δ<i>S</i>∗) and free energy (Δ<i>G</i><sub>ads</sub>) were determined, elucidating the energetics of the corrosion and inhibition processes.
