In the article, based on the experimental studies carried out, a technological process of vacuum nitriding in a pulsating plasma beam is suggested, in which, due to the combination of the advantages of using a pulsating current and gas-thermal cycles of s... see more

The morphologies of the copper deposits obtained by pulsating over­potential regime with prolonged pulse and pause durations from the solution of 0.15 M CuSO4 in 0.50 M H2SO4 at overpotentials lower, higher and belonging to the plateau of limiti... see more

Recent years have seen intensive research on modifying glow-discharge nitriding processes. One of the most commonly used glow-discharge methods includes cathodic potential nitriding (conventional method), and active screen plasma nitriding. Each of these ... see more

The analysis of experimental methods for determination of mechanical losses of power in the hauling electric engines of direct current is presented.

Stand-alone/grid connected renewable energy systems (RESs) require direct current (DC)/DC converters with continuous-input continuous-output current capabilities as maximum power point tracking (MPPT) converters. The continuous-input current feature minim... see more

The analysis of power streams in the schemes of mutual loading of hauling electric machines of direct and pulsating current is presented.

The paper gives the results of studies on hydrodynamic cleaning surfaces with pulsating and cavitating sprays, obtained in a device including local flow resistance — Venturi tube of special geometry. The use of the above technologies to clean the rail tra... see more

Las ondas de tensión apreciablemente distorsionadas, tienen un impacto negativo en el comportamiento de los motores monofásicos asincrónicos de jaula de ardilla. Se deterioran sus indicadores energéticos, se incrementan las vibraciones y el ruido y se red... see more

We revealed regional features of functioning of a large Transbaikalian aeolian morphodynamic system. Natural pre-conditions, current realities and factors of development of aeolian processes are investigated. The paper considers regularities of spatial di... see more
