The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.3 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.7 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.7 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00023 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.11 SJR: 0.244 SNIP: 0.521 CiteScore™:: 3.6 H-Index: 14

摘要

In the present paper, a coupled model of formation of a multilayer coating on the surface of a cylindrical part by deposition from plasma is suggested. The phenomena of thermal diffusion, diffusion heat conduction, mass transfer under the effect of the stress gradient, and of the formation of chemical compounds are taken into account. The rate of coating growth is taken to be a specified function of the velocities and concentration of particles near the surface of the growing coating. The problem is solved numerically. It is shown that during the process of growth the diffusion cross flows, diffusion heat conduction, and thermal diffusion lead to a decrease in the width of the mesoscale transition region between the substrate and the coating. This effect becomes most obvious when the substrate has low thermal conductivity. The account for stresses that develop in the coating–substrate system during the deposition process results in the change of the effective coefficients of transfer and exerts a noticeable effect on the distribution of chemical elements and their compounds in the coating.
