摘要

Abstract >This work investigates the electrochemical behaviour of an AISI 316L stainless steel produced by selective laser melting (SLM) and compares its behaviour with that of wrought stainless steel with similar chemical composition. The SLM stainless steel specimens are tested in the as‐produced condition without stress relief or recrystallization heat treatments. The electrochemical tests are carried out in two electrolytes: 3.5?wt% NaCl solution with neutral pH and with pH of 1.8. >At the macroscale, the microstructure of the SLM specimens is determined by the laser scanning pattern and displays an overlapping network of melt pools. At the microscale, the SLM specimens exhibit a cellular/columnar dendritic structure with submicrometric cell size. Electrochemical measurements highlight a more extended passive range for SLM stainless steel in both neutral and acid electrolytes indicating higher protective properties of the oxide film on SLM specimens. In contrast to the wrought material, the refined microstructure of the SLM specimens promotes a very shallow morphology of attack without deep penetration in the bulk. </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 Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> >本工作调查通过选择性激光熔化（SLM）产生的AISI 316L不锈钢的电化学行为，并将其与具有相似化学组成的锻造不锈钢的行为进行比较。 SLM不锈钢样品在不产生应力浮雕或重结晶热处理的情况下进行测试。电化学试验在两个电解质中进行：3.5·wt％NaCl溶液，中性pH和pH为1.8。</ p> >在宏观上，通过激光扫描图案确定SLM样本的微结构，并显示熔池的重叠网络。在微观尺寸下，SLM样本表现出具有亚细胞细胞尺寸的细胞/柱状树突结构。电化学测量在中性和酸电解质中突出了SLM不锈钢的更加延伸的无源系列，所述酸电解质表明SLM样品上氧化膜的较高保护性能。与锻造材料相比，SLM样本的精细显微组织促进了在散装中没有深入渗透的攻击的非常浅的攻击形态。</ 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>2019年第9期</span><b style="margin: 0 2px;">|</b><span>共13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=Andreatta Francesco&option=202" target="_blank" rel="nofollow">Andreatta Francesco;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Lanzutti Alex&option=202" target="_blank" rel="nofollow">Lanzutti Alex;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Vaglio Emanuele&option=202" target="_blank" rel="nofollow">Vaglio Emanuele;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Totis Giovanni&option=202" target="_blank" rel="nofollow">Totis Giovanni;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Sortino Marco&option=202" target="_blank" rel="nofollow">Sortino Marco;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Fedrizzi Lorenzo&option=202" target="_blank" rel="nofollow">Fedrizzi Lorenzo;</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>Polytechnic Department of Engineering and ArchitectureUniversity of UdineVia del Cotonificio 108‐33100 Udine Italy;</p> <p>Polytechnic Department of Engineering and ArchitectureUniversity of UdineVia del Cotonificio 108‐33100 Udine Italy;</p> <p>Polytechnic Department of Engineering and ArchitectureUniversity of UdineVia del Cotonificio 108‐33100 Udine Italy;</p> <p>Polytechnic Department of Engineering and ArchitectureUniversity of UdineVia del Cotonificio 108‐33100 Udine Italy;</p> <p>Polytechnic Department of Engineering and ArchitectureUniversity of UdineVia del Cotonificio 108‐33100 Udine Italy;</p> <p>Polytechnic Department of Engineering and ArchitectureUniversity of UdineVia del Cotonificio 108‐33100 Udine Italy;</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=316L stainless steel&option=203" rel="nofollow">316L stainless steel;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=localized attack&option=203" rel="nofollow">localized attack;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=selective laser melting&option=203" rel="nofollow">selective laser melting;</a> </p> <div class="translation"> 机译：316L不锈钢;局部攻击;选择性激光熔化;
