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

RÉSUMÉ

The electrical resistivity of titanium dioxide coatings produced by air plasma spraying has been investigated. It is well known that the quality and properties of plasma-sprayed coatings are strongly dependent on the in-flight particle characteristics. The spray parameters such as arc current intensity, total gas flow rate and powder size distribution were changed to understand the influence of these parameters on the particle characteristics before impact and consequently on the microstructure and electrical properties.
The particle states at impact were found to vary strongly with the particle size distribution as revealed by the in-flight characterizations. Small particles were shown to melt more completely in the plasma whereas coarse particles result in a poor microstructure because of the lowering in the particle melting extent. However, the particle parameters influence also the stoichiometry of the ТiO2 coatings making difficult the direct correlation between the microstructure and electrical properties of titanium dioxide coatings.
