The nanocomposite coating was developed using a pulse reverse electrodeposition technique using a Watts bath. The surface morphology of the coatings was analyzed with the help of X‑ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) with EDAX. The coated surface properties like micro-hardness, surface roughness, wear, and corrosion resistance were assessed by Vickers microhardness tester, roughness tester, pin-on-disk equipment, and electrochemical impedance spectroscopy. Specimens with Ni-G nanocomposite coating were post-heat treated at 400°C for 1 h, and oil quenched. With heat treatment, the coated surface exhibited superior properties in comparison with specimens that are not heat treated with a hardness of 467.3 HV, surface roughness of 0.638 µm, wear rate of 8.10 × 10–7mm3/N m, and corrosion protection efficiency of 96.50%. The improved surface properties were due to the grain refinement and particle strengthening, with an increased average crystallite size of 19.6 to 23.82 nm, with a 75.59% reduction in average coefficient of friction achieved for the post-heat-treated surface than the bare surface.","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"61 2","pages":"355 - 367"},"PeriodicalIF":0.8,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145169217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of electrodeposition current density (id) and bath concentration of SiC nanoparticle (CSiC) on different properties of the electrodeposited coatings such as boron content (CB), SiC nanoparticle content; XSiC (wt %), surface roughness; Ra, surface morphology, thickness, corrosion behavior and hardness were examined using inductively coupled plasma (ICP), energy dispersive spectroscopy (EDS), surface roughness profilometry, scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis, potentiodynamic polarization and microhardness testing. The achievements revealed a uniform dispersion of SiC nanoparticle agglomerates throughout the coating cross-section and the formation of spherical surface morphology. A close relationship between coatings’ surface morphology, roughness, hardness, and corrosion resistance with their SiC content has been established. The SiC nanoparticle content of the coatings initially is raised and then lowered via raising both the CSiC and id. While the CB is decreased monotonically with increasing the id. Optimal properties were observed in coatings electrodeposited at id = 1 A/dm2 and CSiC = 4 g/L with a maximum XSiC of 3.6 wt %.

A comprehensive investigation on energy grabbing by GaN, InN, GaInN, GaInSiN, GaInZnN, GaInAgN was carried out including using DFT computations at the CAM-B3LYP-D3/6-311+G(d,p) level of theory. Electromagnetic and thermodynamic properties of GaN, InN, GaInN, GaInSiN, GaInZnN, GaInAgN hetero clusters have been evaluated. The hypothesis of the energy adsorption phenomenon was confirmed by density distributions of CDD, PDOS, and ESP for GaN, InN, GaInN, GaInSiN, GaInZnN, GaInAgN hetero clusters. The two hetero clusters of GaInZnN and GaInAgN with the fluctuations of In, Ga, N and transition metals of Zn, Ag have indicated the same sensitivity graph of electric potential via charge distribution with (R_{{{text{Zn}}/{text{Ag}} - {text{GaInN}}}}^{2}) = 0.9998. Therefore, it can be considered that zinc and silver atoms in the functionalized GaInZnN and GaInAgN may have more effective sensitivity for admitting the electrons in the status of energy adsorption mechanism. Furthermore, GaInAgN is potentially advantageous for certain high-frequency applications requiring solar cells for energy storage. The advantages of silver over indium gallium nitride include its higher electron and hole mobility, allowing silver doping devices to operate at higher frequencies than silicon and zinc doping devices. As a matter of fact, it can be observed that doped hetero clusters of GaInZnN and GaInAgN might ameliorate the capability of GaInN in solar cells for energy storage.","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"61 2","pages":"301 - 318"},"PeriodicalIF":0.8,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145170182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the development of multifunctional transparent anti-fouling coatings that meet practical requirements without compromising their properties remains a major challenge. This paper presents an innovative approach to address this issue by combining self-cleaning and durability through the incorporation of specific functional materials. Polydimethylsiloxane (PDMS) and methyl o-aminobenzoate (MA) were introduced to achieve these desired properties, respectively. Additionally, bisphenol A diglycidyl ether (BADGE) and 1,3-bis(3-aminopropyl)tetramethyldisiloxane (TMDS) were employed as coating substrates to enhance the mechanical strength of the coating. The structural composition, elemental analysis, and surface morphology of the coatings were thoroughly characterized using advanced techniques. The hydrophobicity, optical transparency, self-cleaning ability, and durability of the coatings were extensively evaluated. Experimental results demonstrated that the developed fluorine-free transparent hydrophobic coating exhibited excellent performance across multiple criteria: it showed outstanding hydrophobicity and transparency, superior self-cleaning capability, exceptional resistance to wear, water shock, and strong acid and alkali properties.","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"61 2","pages":"319 - 330"},"PeriodicalIF":0.8,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145170632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it was interesting to evaluate the influence of surface modification of detonation nanodiamonds on their interaction with biological objects. The detonation nanodiamonds were graphitised, chlorinated and aminated, and thoroughly investigated. The application of a complex of research methods of scanning electron microscopy SEM + EDX, IR spectroscopy, dynamic light scattering, X-ray diffractometry (XRD) allowed to reveal the peculiarities of physical chemistry of DND surface. It was found that during chlorination of DND the concentration of chlorine atoms increased from 0.05 to 6.60 wt %. Differences in the agglomeration of particles in water medium were found for the original and modified samples. The study of biological properties revealed the following. It was determined by the MTT method that DND-Cl had the most negative effect on Vero cell culture and DND-NH2 had the least negative effect on Vero cell culture. At DND-NH2 concentrations of 0.01 mg/mL and below, up to 75% of MDCK cells did not lose their functionality and were able to reproduce influenza A/Moscow/212/2014(H3N2) virus, and the virus titre after leaving the cells ranged from 16 to 64 HA.
