In particular, nitinol is one of the best materials for the production of intracoronary and brain arterial stents. The reliability of such a stent is a matter of life for a patient, because malfunctions of almost any kind may result in lethal damages. Although nitinol is chemically quite passive, a stent has to pertain good mechanical stability for many years, desirable many dozens of years. Another problem presenting a potential risk is nickel, whose corrosion may produce toxic substances. Wires of which a stent is produced are in dynamic stress so that the issue of fretting corrosion is especially important.</p></div> Fri, 30 Nov 2018 13:28:41 +0000 alexL 28 at https://al-chemist.info Corrosion protection of magnesium alloys by PEO https://al-chemist.info/index.php/corrosion-protection-magnesium-alloys-peo <span property="schema:name" class="field field--name-title field--type-string field--label-hidden">Corrosion protection of magnesium alloys by PEO</span> <span rel="schema:author" class="field field--name-uid field--type-entity-reference field--label-hidden"><span lang="" about="/index.php/user/20" typeof="schema:Person" property="schema:name" datatype="">alexL</span></span> <span property="schema:dateCreated" content="2018-11-30T13:24:34+00:00" class="field field--name-created field--type-created field--label-hidden">Fri, 11/30/2018 - 15:24</span> <div property="schema:text" class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>(The project is performed in the cooperation with Prof. Michael Zinigrad)</p> <p>Plasma electrolytic oxidation (PEO) is a technology allowing obtaining hard wear- and corrosion-resistant coatings in the form of thick and highly-adhesive oxide layer on aluminum, magnesium and other metal surfaces. Although the processes in plasma processing occur in electrolyte solutions under the action of electric charge and therefore can be classified as electrochemical, they are significantly different than "conventional" electrochemical processes, in which relatively small currents and voltages cause relatively tranquil chemical reactions.</p> <figure role="group" class="caption caption-img"><img alt="Plasma Electrolytic Oxydation" data-entity-type="file" data-entity-uuid="cb81dc4f-0b20-4624-b906-12ba14bf7889" src="/sites/default/files/inline-images/impeller.JPG" /><figcaption>Plasma Electrolytic Oxydation</figcaption></figure><p><br /><br /> For a conventional electrochemical (for instance, electroplating) processing, anodic reactions can sometimes cause the passivation of the electrode surface due to formation of impenetrable to reactants (or products). For aluminum or magnesium (or some other metals) such passivation occurs when the coating is only &lt;10 nm thick. Such thickness cannot provide the metal any reliable protection against abrasion or corrosion. What distinguishes the PEO from a regular electroplating, is the continuation of the anodic process. As the surface has been passivated by non-conductive oxide coating, the potential difference between the metal and the electrolyte keeps increasing. It increases until it has become too high for the dielectric coating and a microscopic plasma discharge breaks the coating. This breakdown results in the formation of a bit thicker coating, which will be broken again in the course of the next cycle, under a bit higher potential difference. The cycles continue until desired coating thickness has been achieved (normally, 20-50 μm).</p> <p>Thus produced oxide layer presents considerable protection of magnesium alloys to corrosion processes in aggressive environments. By properly adjusting some parameters of PEO we can decelerate corrosion rate by 10 and more times.</p></div> Fri, 30 Nov 2018 13:24:34 +0000 alexL 27 at https://al-chemist.info Corrosion of magnesium alloys https://al-chemist.info/index.php/corrosion-magnesium-alloys <span property="schema:name" class="field field--name-title field--type-string field--label-hidden">Corrosion of magnesium alloys</span> <span rel="schema:author" class="field field--name-uid field--type-entity-reference field--label-hidden"><span lang="" about="/index.php/user/20" typeof="schema:Person" property="schema:name" datatype="">alexL</span></span> <span property="schema:dateCreated" content="2018-11-30T13:21:27+00:00" class="field field--name-created field--type-created field--label-hidden">Fri, 11/30/2018 - 15:21</span> <div property="schema:text" class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><figure role="group" class="caption caption-img"><img alt="Corrosion products on a magnesium alloy surface" data-entity-type="file" data-entity-uuid="fb5d4e55-db55-481d-a67d-70332c7bfe91" src="/sites/default/files/inline-images/mg_corr.jpg" /><figcaption>Corrosion products on a magnesium alloy surface</figcaption></figure><p>The mechanism of corrosion processes in magnesium and its alloys is very complex and not completely understood, in spite of the large number of studies. While it is clear that the corrosion of magnesium is highly localized (often it occurs on the level of structure grains and intergranular boundaries) and the key role in the corrosion process belongs to impurities, it is much less clear why the same phases in a magnesium alloy may sometimes accelerate the corrosion and sometimes inhibit it. It is known that the corrosion behavior of magnesium alloys strongly depends on the technology of casting and subsequent cold and hot working, but the details of this dependance are known only for some cases. Even the measurement of the corrosion rates of magnesium alloys is a problem, because different techniques of measurement present very different results, a minor error in the preparation of a specimen completely changes the rate and even the character of the corrosion process; and even when specimens have been prepared ideally perfect, significant deviation are observed. Particular interest present MRI series magnesium alloys patented by the Dead Sea Magnesium and Volkswagen. Being relatively new, these alloys have been only poorly studied, which makes such a research "hot" and actual. The research involves a systematic comparison of the measurements of the corrosion rates by different techniques, both electrochemical and purely chemical. The comparison will hopefully reveal the details of the corrosion mechanisms and will also allow the choice of the most appropriate test technique. The corrosion behavior of Mg alloys is measured by the open circuit potential (OCP) measurements, electrochemical impedance spectroscopy (EIS), linear polarization tests (LPR), linear sweep voltammetry (by Tafel extrapolation) and cyclic voltammetry, gas evolution and mass loss in neutral 3.5 wt% NaCl solution. The validity of the above techniques for the evaluation of corrosion characteristics of magnesium alloys is compared. </p></div> Fri, 30 Nov 2018 13:21:27 +0000 alexL 26 at https://al-chemist.info Research synopsis https://al-chemist.info/index.php/research-synopsis <span property="schema:name" class="field field--name-title field--type-string field--label-hidden">Research synopsis</span> <span rel="schema:author" class="field field--name-uid field--type-entity-reference field--label-hidden"><span lang="" about="/index.php/user/20" typeof="schema:Person" property="schema:name" datatype="">alexL</span></span> <span property="schema:dateCreated" content="2018-11-30T13:19:23+00:00" class="field field--name-created field--type-created field--label-hidden">Fri, 11/30/2018 - 15:19</span> <div property="schema:text" class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><ul><li><a href="corrosion-magnesium-alloys">Corrosion of magnesium alloys </a></li> <li><a href="corrosion-protection-magnesium-alloys-peo">Corrosion protection of magnesium alloys by PEO</a></li> <li><a href="corrosion-nitinol">Corrosion of Nitinol</a></li> <li><a href="electrochemistry-aqueous-amine-systems">Electrochemistry of aqueous amine systems</a></li> </ul></div> Fri, 30 Nov 2018 13:19:23 +0000 alexL 30 at https://al-chemist.info About myself https://al-chemist.info/index.php/about-myself <span property="schema:name" class="field field--name-title field--type-string field--label-hidden">About myself</span> <span rel="schema:author" class="field field--name-uid field--type-entity-reference field--label-hidden"><span lang="" about="/index.php/user/20" typeof="schema:Person" property="schema:name" datatype="">alexL</span></span> <span property="schema:dateCreated" content="2018-11-30T13:10:33+00:00" class="field field--name-created field--type-created field--label-hidden">Fri, 11/30/2018 - 15:10</span> <div property="schema:text" class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p><img alt="Alex Lugovskoy" data-entity-type="file" data-entity-uuid="147f807a-db77-4ccb-97ba-d84d9aaf146e" height="293" src="/sites/default/files/inline-images/alex_0.jpg" width="292" /></p> <h6>Dr. Alex Lugovskoy</h6> <p>The Department of Chemical Engineering</p> <p>Milken Campus, Ariel University</p> <p>office: 2.2.18,<br /> Tel. +972-3-9765785<br /> e-mail: <a href="mailto:lugovsa@ariel.ac.il">lugovsa@ariel.ac.il</a></p> <p>Alex received his PhD in Physical Chemistry in Bar-Ilan University.
