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

ABSTRAKT

Two different power supplies used for dc arc plasma spraying unit with water stabilized plasma torch were compared - classical thyristor controlled unit with the frequency of the current ripple 300 Hz and the rectifier with the high frequency converter and frequency of the current modulation 30 kHz. For the both types of power supply the arc characteristics were measured, time averaged plasma jet properties were determined from spectroscopic measurements and plasma jet fluctuations were analysed on the basis of diagnostics with an array of high frequency photodiodes. The properties of coatings sprayed with the two power supplies were compared. While time averaged profiles of plasma jet were the same for the both power supplies, the fluctuations of plasma jet differed substantially. Also the dynamic arc voltage characteristics of the arc were different and could be described by modified Cassie equation. The differences of properties of TiO coatings deposited with the use of the two power supplies were not significant.
