Publikováno v: Steel in Translation. 50:387-390

The effect of manual electric arc surfacing modes of low-alloy 09G2S steel by T-590 electrodes on their structure and hardness has been investigated. It is shown that pulse-arc surfacing of coatings by electrodes forms a fine-dendritic structure of t

Structure and properties of coatings based on chromium and boron carbides deposited in a relativistic electron beam

Autor: M. V. Perovskaya, V. V. Shmakov

Publikováno v: PROCEEDINGS OF THE INTERNATIONAL CONFERENCE ON PHYSICAL MESOMECHANICS. MATERIALS WITH MULTILEVEL HIERARCHICAL STRUCTURE AND INTELLIGENT MANUFACTURING TECHNOLOGY.

This paper deals with wear-resistant and corrosion-resistant coatings obtained by electron-beam surfacing in a beam of relativistic electrons of powder mixtures of chromium carbide with boron carbide in various weight ratios and with changes in the r

Publikováno v: MECHANICS, RESOURCE AND DIAGNOSTICS OF MATERIALS AND STRUCTURES (MRDMS-2020): Proceeding of the 14th International Conference on Mechanics, Resource and Diagnostics of Materials and Structures.

The paper proposes a possible approach to estimating the residual life of welded joints, based on a phenomenological model of damage accumulation and fracture. The adequacy of the developed approach is confirmed by comparison with experimental data o

Influence of surfacing modes on the characteristics of heat and mass transfer of the electrode material and the formation of a dispersed structure in coatings

Autor: V. P. Bezborodov, M. V. Perovskaya, A. S. Nepomnyashchiy, Yu. N. Saraev, V. M. Semenchuk

Publikováno v: PROCEEDINGS OF THE INTERNATIONAL CONFERENCE ON PHYSICAL MESOMECHANICS. MATERIALS WITH MULTILEVEL HIERARCHICAL STRUCTURE AND INTELLIGENT MANUFACTURING TECHNOLOGY.

The paper studies the effect of electric arc surfacing modes with T-590-N and EN-60M coated electrodes on the physical, mechanical and operational properties of coatings applied to low-alloy steel 09G2S. It is shown that the characteristics of heat a

Electron-beam deposition of chromium carbide–based coatings with an ultradispersed structure or a nanostructure

Autor: I. M. Poletika, M. V. Perovskaya, S. F. Gnyusov, S. F. Ivanov

Publikováno v: Russian Metallurgy (Metally). 2016:1275-1282

Coatings with an ultradispersed structure and a nanostructure, which have a high wear resistance, corrosion resistance, and a satisfactory ductility, are fabricated by electron-beam vacuum-free deposition of a powder mixture of chromium carbide, chro
