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

SINOPSIS

For copper and chromium, used in alloy component electrodes of vacuum circuit breakers, the cathode spots are initiated on micron meter spikes above the surface of the electrode, they are considered as cylinders with a height equivalent. After spraying of these peaks the cathode spot reaches the surface of the electrode on which it will expand according to a proposed model. The two studied materials have quite different thermophysical properties, but they lead to comparable results. In both cases the erosion of cylindrical spikes is due to the flow of energy provided by the cathode spot, the mechanism is different from those found for the molten bridge or for fuses where the Joule effect is the only factor to take into account.
