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

ABSTRACT

Results of laser-induced oxidation (100−500 Hz frequency, 1064 nm wavelength, and 1 ns pulse duration) and formation of micro- and nanostructures on the surface of high-quality structural carbon steel (0.42 wt.% C, 0.5 wt.% Mn, 0.25 wt.% Cr) are presented. The steel samples were irradiated in ambient air, water, 3% hydrogen peroxide, and ethanol by a series of laser pulses at a power density of (3.2−4.4)·109 W/cm2, which is close to the ablation threshold. The surface structures were examined by optical microscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, and Raman spectroscopy. Different kinds of structures detected on the steel surface and the efficiency of oxide formation depend strongly on both the liquid or gaseous environments and the parameters of laser treatment. It was found that the efficiency of nano/microstructures and oxides formation on structural steel is especially expressed for samples irradiated in air and hydrogen peroxide environments.
