This hybrid method of energy treatment for a liquid metal system implements a complex superposition of electromagnetic fields, which determines the parameters of the thermal-force impact on the treated object. The functional capabilities of this method were analyzed through numerical experiments using simulation modeling. The obtained results demonstrated potential treatment modes capable of actively enhancing the incubation processes of crystallization, which ultimately allows one to find conditions for improving the structure and properties of the cast metal. Thus, the combination of simultaneous conduction and induced current treatment modes consistently led to a stronger impact on the liquid metal system compared to applying them separately. It was found that the genesis of the electromagnetic field superposition is mainly concentrated within the skin layer near the melt surface. The time characteristics of the electric and magnetic fields become nonlinear, which amplifies energy fluctuations within the system. At the same time, the amplitude values of the combined electromagnetic field characteristics increase by almost an order of magnitude, significantly enhancing the integral amplitude of the force impact on the melt. Thus, the simulation modeling results confirmed the innovative potential of the hybrid method of treating the melt simultaneously with conduction and induced currents for foundry applications.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"62 2","pages":"141 - 149"},"PeriodicalIF":0.7,"publicationDate":"2026-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147714838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, composite coatings made of Fe-based metallic glass reinforced with titanium diboride (TiB2) were prepared for the first time. For this purpose, the method of electrospark deposition with a nonlocalized electrode consisting of iron granules, TiB2 powder, and amorphizing powder in various ratios was used. The thickness of the prepared composite coatings on 45 steel ranged from 37 to 44 μm. It was shown that the coating structure contains TiB2 particles, the maximum concentration of which is achieved at a titanium diboride to multicomponent powder ratio of 1 to 5. The surface roughness of the coatings had close values of 8.3–8.8 μm. It was found that the wetting angle of coatings reinforced with TiB2 with distilled water changes from 80.4° to 91.4°, whereas the hydrophobicity of the amorphous coating without TiB2 was higher (95.4°). It was found that reinforcing the amorphous coating with TiB2 allows increasing its microhardness from 10.0 to 12.5–14.65 GPa. The average values of the friction coefficient of coatings ranged from 0.76 to 0.58. The coating with the highest concentration of titanium diboride had the highest wear resistance. Its use allows reducing the wear of parts made of steel 45 almost ten times. It has been established that reinforcement of the amorphous coating with TiB2 according to the proposed method does not worsen its oxidation resistance. In general, the use of the developed coatings allows a 13- to 20-fold increase in the oxidation resistance of products made of steel 45 at 700°C.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"62 1","pages":"50 - 59"},"PeriodicalIF":0.7,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147588412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

X-ray powder diffraction analysis determined the real structure of this material as Al/n-Al2O3/p-CdTe/n-MoO3/Mo. In its final form, it is represented as n+–p–n, where the base (p-CdTe) is in contact on both sides with wide-bandgap thin oxide layers of n-Al2O3 and n-MoO3 so that the n+–p junction is ideal and the p–n junction is nonideal. Upon the application of reverse bias (when a positive (+) voltage is applied to Al and a negative (–) to Mo), minority nonequilibrium charge carriers accumulate near the ideal contact, which results in an extended sublinear region in the reverse current–voltage characteristic of the structure before and after irradiation. This is explained within the framework of the theory of injection depletion effect by the injection of electrons from the rear junction n-MoO3/p-CdTe and by the emergence of diffusion and drift currents directed toward each other in the base of the structure. The shape and length of the sublinear region are preserved because of the high value of the frontal–ideal potential barrier n+–p, while in the range of various irradiation doses Φ (106, 107, 108, and 109 rad), the distribution profile of nonequilibrium charge carriers in the base of the structure remains virtually unchanged.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"62 1","pages":"87 - 94"},"PeriodicalIF":0.7,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147588566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The compound antimicrobial activity was evaluated. The compound showed a moderate to strong inhibitory action towards a selection of Gram-positive (S. aureus, S. epidermidis), Gram-negative (Klebsiella spp., and E. coli), and fungal (Candida albicans) species, and its activity increased at higher concentrations. The compound electronic structure, molecular orbitals, and vibrational properties were studied using DFT and TD-DFT calculations. The bioactivity exhibited was explained by the proposed charge transfer mechanism evinced by the HOMO-LUMO energy gap and a dipole moment as well as the bioactivity exhibited by the studied compound. This is the chalcone derivative potential applications in electrophysiology. The chalcone derivative is a promising candidate for further study as an antimicrobial surface-active agent or as a functional material in electrochemical devices and coatings, as suggested by the synergy between experimental and theoretical data matching.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"62 1","pages":"74 - 82"},"PeriodicalIF":0.7,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147588571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address challenges such as coarse grains and porosity caused by concentration polarization during traditional direct current plating, ultrasonic intervals of varying durations were introduced. The surface morphology, crystallographic orientation, grain size, and corrosion resistance were analyzed using scanning electron microscopy, X-ray diffraction, and electrochemical techniques. Results reveal that continuous ultrasound and short-interval pulsing promote (220) texture and yield finer grains, with sample #3 exhibiting the strongest (220) orientation and smallest grain size. Longer intervals shift the preferred orientation to (200), enhance coating compactness and improve thermodynamic stability (higher open-circuit potential), but do not necessarily result in better corrosion resistance. Notably, sample #1 demonstrated the lowest corrosion current density and a balanced polarization resistance, indicating the best overall electrochemical protection. This study highlights the importance of ultrasonic interval tuning to balance structural and electrochemical properties in functional nickel coatings.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"62 1","pages":"25 - 35"},"PeriodicalIF":0.7,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147588375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
