Microstructure and Properties of a Laser Hardened Non-composite Rolling Mill Liner 作者:Qiu, XW (Qiu, X-W.)[ 1 ] LASERS IN ENGINEERING 卷: 34 期: 1-3 页: 107-116 出版年: 2016 查看期刊信息 LASERS IN ENGINEERING 出版商 OLD CITY PUBLISHING INC, 628 NORTH 2ND ST, PHILADELPHIA, PA 19123 USA ISSN: 0898-1507 eISSN: 1029-029X 研究领域 Materials Science Optics 摘要 Mill liners play a role in protecting mill stand. In order to change the traditional status that rolling mill liner can not be manufactured with a single material, laser transformation hardening was carried out with a CO2 laser on 45 steel surfaces and produced a new type non-composite liner. The microstructure and properties were researched by means of a scanning electron microscope (SEM), X-ray diffraction (XRD), micro-hardness tester, abrasive wear testing machine and electrochemical workstation. The results indicate that the microstructure of the laser transformation hardened layer fine and homogeneous, mainly composed of Fe3C, Fe-Cr and Cr3C2, the hardness is about three-times that of the substrate, the relative wear resistance increased significantly, which can reached the technical requirements liner needed. The laser transformation hardened layer plays an important protective role in 3.5% NaCl environment. 关键词 作者关键词:CO2 laser; 45 steel; laser hardening; non-composite rolling mill liner; microstructure; microhardness; wear resistance 作者信息 通讯作者地址: Qiu, XW (通讯作者) Sichuan Coll Architectural Technol, Dept Mat Engn, Deyang 618000, Sichuan Provinc, Peoples R China. 地址: [ 1 ] Sichuan Coll Architectural Technol, Dept Mat Engn, Deyang 618000, Sichuan Provinc, Peoples R China 电子邮件地址:fallenrain922@163.com 基金资助致谢 基金资助机构 授权号 Key Science and Technology Research Projects of Deyang City, Sichuan Province, China 查看基金资助信息关闭基金资助信息 The author gratefully acknowledges the support for this research the Key Science and Technology Research Projects of Deyang City, Sichuan Province, China. 出版商 OLD CITY PUBLISHING INC, 628 NORTH 2ND ST, PHILADELPHIA, PA 19123 USA 类别 / 分类 研究方向:Materials Science; Optics Web of Science 类别:Materials Science, Multidisciplinary; Optics 文献信息 文献类型:Article 语种:English 入藏号: WOS:000389756300007 ISSN: 0898-1507 eISSN: 1029-029X 其他信息 IDS 号: EE6XA Web of Science 核心合集中的 "引用的参考文献": 10 Web of Science 核心合集中的 "被引频次": 0 JCR® 类别 JCR 分区 MATERIALS SCIENCE, MULTIDISCIPLINARY Q4 OPTICS Q4 数据来自第 2015 版 Journal Citation Reports® |
