摘要

Abstract >The requirement for lighter vehicles in the automotive industry promotes designs based on the combination of different metallic alloys. Such an approach, however, leads to galvanic‐corrosion risks, which compromise the durability of vehicles. One proposal to minimize such risks is to separate some of the chassis components by a Zn washer. The present work uses the finite element method to evaluate such an innovative design. The capacity of the washer to protect its aluminum alloy and carbon steel neighbors is assessed. As a worst‐case scenario, the bare metals are in contact with NaCl solution. Two electrolyte layer thicknesses are assumed: in the micrometer and in the millimeter range. Each case requires different mathematical models. For the thin film case, the zinc washer is able to protect its neighbors from corrosion. However, it sustains large corrosion rates, and thus its protection is effective only during short periods. Furthermore, as the Zn surface degrades and thus recesses, the “protective field” is blocked by the neighboring metal‐walls. The thicker the electrolyte layer, the weaker the Zn protective capability and, at some point, the corrosion of the aluminum alloy is unavoidable. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract XML：lang =“en”type =“main”> <标题类型=“main”>抽象</ title> >汽车工业中较轻车辆的要求促进了基于不同金属合金的组合的设计。然而，这种方法导致电抗腐蚀风险，这损害了车辆的耐久性。最小化这种风险的一个提议是通过Zn洗衣机分离一些底盘组件。目前的工作使用有限元方法来评估这种创新设计。评估了垫圈保护其铝合金和碳钢邻居的能力。作为最坏情况的情况，裸金属与NaCl溶液接触。假设两个电解质层厚度：在千分尺和毫米范围内。每种情况都需要不同的数学模型。对于薄膜壳，锌垫圈能够保护其邻居免受腐蚀。然而，它维持了大的腐蚀速率，因此其保护仅在短时间内有效。此外，随着Zn表面劣化并且因此凹陷，“保护域”被相邻金属壁阻挡。电解质层越厚，抗锌保护能力越弱，在某些时候，铝合金的腐蚀是不可避免的。</ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-24514/'>《Materials and Corrosion》</a> <b style="margin: 0 2px;">|</b><span>2020年第3期</span><b style="margin: 0 2px;">|</b><span>共8页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Ruiz‐Garcia Allan&option=202" target="_blank" rel="nofollow">Ruiz‐Garcia Allan;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Mayen‐Mondragon Rodrigo&option=202" target="_blank" rel="nofollow">Mayen‐Mondragon Rodrigo;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Genesca Joan&option=202" target="_blank" rel="nofollow">Genesca Joan;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Morales‐Murillo Esteban&option=202" target="_blank" rel="nofollow">Morales‐Murillo Esteban;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Taha‐Tijerina Jaime&option=202" target="_blank" rel="nofollow">Taha‐Tijerina Jaime;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Montoya Rodrigo&option=202" target="_blank" rel="nofollow">Montoya Rodrigo;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Facultad de Química Departamento de Ingeniería Metalúrgica Polo Universitario de Tecnología AvanzadaUniversidad Nacional Autónoma de MéxicoApodaca México;</p> <p>Facultad de Química Departamento de Ingeniería Metalúrgica Polo Universitario de Tecnología AvanzadaUniversidad Nacional Autónoma de MéxicoApodaca México;</p> <p>Facultad de Química Departamento de Ingeniería Metalúrgica Polo Universitario de Tecnología AvanzadaUniversidad Nacional Autónoma de MéxicoApodaca México;</p> <p>Tecnologías de Materiales avanzadosMetalsa S.A. de C.V.Apodaca México;</p> <p>Tecnologías de Materiales avanzadosMetalsa S.A. de C.V.Apodaca México;</p> <p>Facultad de Química Departamento de Ingeniería Metalúrgica Polo Universitario de Tecnología AvanzadaUniversidad Nacional Autónoma de MéxicoApodaca México;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/7194.html" title="金属腐蚀与保护、金属表面处理">金属腐蚀与保护、金属表面处理;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=galvanic couples&option=203" rel="nofollow">galvanic couples;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=modeling&option=203" rel="nofollow">modeling;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=thin electrolyte films&option=203" rel="nofollow">thin electrolyte films;</a> </p> <div class="translation"> 机译：电流耦合;建模;薄电解质薄膜;
