It was determined that in an electrolyte containing 1.75 g/L KOH+1 g/L Na2SiO3+2 g/L NaAlO2, with an increase in current density from 15 A/dm2 to 50 A/dm2, the phase composition of the coating changes. In the three-phase state (al... see more

Coatings with a thickness of about 100 µm were obtained by microarc oxidation of technically pure aluminum and aluminum alloyed with copper and zinc in an alkaline silicate electrolyte at a current density of ~20 A/dm2. The results of studying t... see more

This paper presents new results of transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD) and atomic force microscopy (AFM) investigation of the structure-phase compositions of coatings on the base of Ni and Co... see more

The crystal structure, phase composition, and electrochemical properties of the materials obtained by sintering of (LaNi3+Mg+Ni) powder mixture in the temperature range 640–1020°? have been investigated. Experimental results show that, at temperatures of ... see more

The research is aimed at studying the species composition, dynamics of the number and harmfulness of dominant pests, which is extremely important for the development and improvement of elements of the onion protection system. After all, the analysis of li... see more

Purpose. The aim of the research was to study the effect of electrolysis conditions during microarc oxidation in an alkaline silicate electrolyte on the regularities of the growth kinetics, structural-phase state, and hardness of MAO coatings on casting a... see more

The effect of electrolysis conditions with different electrolyte compositions on the growth kinetics, phase-structural state, and hardness of coatings obtained by microarc oxidation (MAO) on the D16 aluminum alloy (base – aluminum, main impurity Cu) was s... see more

The influence of electrolysis conditions at different electrolyte compositions on the phase formation and properties of coatings obtained by microarc oxidation (MAO) on an aluminum alloy AMg6 was studied. For electrolysis, three types of electrolytes were... see more

In the work the regularities of the influence of the chemical composition of steels for railway wheels on their mechanical properties by means of complex physical and chemical composition criteria. Based on the results of laboratory experiments and of ana... see more
