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

摘要

This work is devoted to the comparative study of diffuse and contracted forms of the cathode arc attachment. We studied DC free-burning atmospheric pressure argon arc at currents 20 ÷ 200 A. The arc was oriented vertically with a cathode at the bottom. The cathode rod of 2 mm in diameter was made of pure tungsten. The water-cooled plane copper anode was set 10 mm above the cathode tip. Measurement results have showed: 1) a surface temperature and its distribution along the cathode rod axis are differed considerably one from another in two attachment forms; 2) in the case of the contracted form, the near-cathode plasma temperature exceeds greatly that in the diffuse form and is about 3 eV at its maximum in the immediate vicinity of the cathode tip (so, to determine the plasma temperature the ArIII lines radiation was used); 3) a plasma temperature in the contracted attachment root doesn't depend on current; 4) for both attachment forms the current densities on the cathode surface don't depend on current, being in the contracted form the current density is about four times higher than in diffuse one and comes to (1 ÷ 1.5)·104 A/cm2. Data obtained were compared with published experimental results and calculations.
