Self-organization mechanisms of metastable dissipative structures during friction depending on base and oil functional additives for hypoid gears are considered. Research was conducted a software-hardware complex with simulation gears’ operation in rolling slipping conditions start-stop mode. Indicators formation wear-resistant include the following: improvement antifriction characteristics, lu...

In this paper, we study the strength and fracture mechanism of cast magnesium alloy Mg-Zn-Ca (1.0 % Zn, 0.2 Ca) for medical applications after equal-channel angular pressing (ECAP) in comparison with initial condition (after homogenization annealing). Mechanical tests included tensile torsion samples a diameter 3 mm impact V-shaped stress raiser. The microrelief all fractures was studied Phenom...

Editor First described by Manstein and Anderson, fractional techniques have revolutionized the management of numerous dermatological conditions, leading to the development of fractional lasers and fractional radiofrequency devices. A retrospective study was carried out on consecutive patients treated with a non-insulated microneedle fractional radiofrequency (NIMFRF) device: Secret (Ilooda, 2 K...

Joint replacement is being actively developed within modern orthopedics. One novel material providing fast implantation is bioactive coatings. The synthesis of targeted nanocoatings on metallic nanotitanium surface is reported in this paper. TiO₂-based micro- and nanocoatings were produced by sol-gel synthesis using dip-coating technology with subsequent fast (shock) drying in hot plate mode at...
