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

摘要

The aim of this paper is to study the influence of the electrolyte temperature on the porosity of the AMg2 (Al 5052) aluminum alloy and also to obtain a highly ordered porous anodic alumina (PAA) with adjustable pore sizes by using high-voltage electrochemical oxidation of the mixture of phosphoric, boric, and oxalic acids. The surface morphology and elemental composition of PAA are characterized by scanning electron microscopy (SEM) and energy-dispersive X-ray spectrometry (EDS). Moreover, the pore formation mechanism is also discussed. The results show that the nanopore arrays in all the PAA samples are in a highly regular arrangement and the pore size ranges between 50−240 nm. However, pore widening due to chemical dissolution of the oxide by the electrolyte led to films with cone-shaped pores (hexagonal shapes or a honeycomb-like structure). This phenomenon became more pronounced with increasing electrolyte temperature. EDS analysis suggests that the main elements of the PAA are oxygen, aluminum, and a small amount of phosphorus, carbon, sodium, and magnesium.
