Promising technological process of strengthening threaded tools joint of a drill string is gasthermalcyclic ion-plasma nitriding. However, the formation of hardened surface layers by the specified process, despite the experience gained, has a some unresol... see more

Glow discharge nitriding is being used increasingly more often for modifying the properties of titanium and its alloys with the aim to increase their frictional wear resistance, fatigue strength, and, in the case of medical applications, to eliminate the ... see more

A study has been made of permalloy (iron-nickel) contacts of reed switches before and after ion-induced surface modification using atomic force and optical microscopy, Auger electron and X-ray photoelectron spectroscopy. It has been found that the formati... see more

The physical properties including the mechanical, optical and electrical properties of Ti nitrides and silicides are very attractive for many applications such as protective coatings, barriers of diffusion, interconnects and so on. The simultaneous format... see more

In this work we investigated the ambipolar diffusion in electronegative plasma. The case of a plasma containing electrons, one kind of negative ions and two kinds of positive ions is considered. The formulas for the coefficient of ambipolar diffusion are ... see more

A rigorous theoretical investigation has been made on nonlinear dust-ion-acoustic (DIA) solitary waves (SWs) in a multi-ion dusty plasma system, consisting of inertial positive and negative ions, and arbitrary charged stationary dust. The dust particles h... see more

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

Generation of metal plasma in vacuum arc discharge is always accompanied by a production of macroparticles (MPs). The MP contamination in coatings is the most important technological problem in plasma immersion ion implantation (PIII). For the case of PII... see more

The behavior of nonlinear quantum dust ion acoustic (QDIA) shock waves in a collisionless, unmagnetized plasma consisting of inertialess quantum electrons and positrons, classical cold ions and stationary negatively charged dust grains with dust charge va... see more
