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: 0.4 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: 0.1 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: 0.00005 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: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

ABSTRACT

Results of experimental investigation of copper cathode erosion in magnetically driven arc versus arc current, arc velocity and electrode surface temperature are presented. The experiments showed the presence of two different erosion regimes as function of current and temperature. First, erosion slowly grows for low values of these parameters, then, a sudden increase of erosion occurs. A critical temperature of about 500-600 К for this transition was found for magnetic fields in the range 0.01-0.35 Т. We observed that, besides the decrease of erosion for low arc velocities, erosion can also increase for high velocities, contrary to what was expected. A reasonable agreement to predictions of a previously published erosion model is obtained.
