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

Краткое описание

Materials which exhibit high specific heat and melting enthalpy combined with a low density, like boron carbide B4C, are difficult to melt by plasma spraying under standard spray conditions. Moreover, the injection of this low-density powder in the plasma jet is critical, especially when fine particles are used. The optimization of the plasma-forming gas composition may make the penetration of the particles in the gas flow easier, and improve their melting state. This paper presents an investigation of the effect of the composition of ternary gas mixtures of argon, helium and hydrogen on B4C particles heating and acceleration. The particle injection and the resulting spray pattern in the jet were controlled by using a 1D imaging technique. The particle velocity distribution was measured with a laser Doppler anemometer and the particle overall temperature with a high-speed pyrometer.
