目的：研究严重影响磷化板表面质量的冷轧基板表面黑变缺陷的成因及机理。方法通过金相分析、扫描电镜电子探针、X射线光电子能谱法、辉光放电光谱法、X射线衍射等分析方法,对黑变缺陷进行系统的分析,并对其形成机理进行探讨。结果黑变缺陷样板表面C元素含量约为正常样板的17倍,C元素主要以石墨形式存在。结论由于带钢表层富集大量以石墨形式存在的C元素,诱发了钢板表面黑变缺陷,其形成原因与钢板化学成分、表面状态以及退火等工艺密切相关。
目的：研究嚴重影響燐化闆錶麵質量的冷軋基闆錶麵黑變缺陷的成因及機理。方法通過金相分析、掃描電鏡電子探針、X射線光電子能譜法、輝光放電光譜法、X射線衍射等分析方法,對黑變缺陷進行繫統的分析,併對其形成機理進行探討。結果黑變缺陷樣闆錶麵C元素含量約為正常樣闆的17倍,C元素主要以石墨形式存在。結論由于帶鋼錶層富集大量以石墨形式存在的C元素,誘髮瞭鋼闆錶麵黑變缺陷,其形成原因與鋼闆化學成分、錶麵狀態以及退火等工藝密切相關。

ABSTRACT:Objective To study the causes and mechanism of blackening defect seriously affecting the phosphating quality of cold-rolled steel sheet. Methods Blackening defect was systematically analyzed by methods of metalloscope, EDS, XPS, GDS, XRD, etc. , and the formation mechanism was discussed. Results The C element content of the surface of defect steel sheet was near-ly 17 times that of normal steel sheet. The C element of the surface of defect steel sheet mainly existed in the form of graphite. Con-clusion Blackening defect was caused by massive accumulation of C element in the form of graphite on the surface layer of steel strip, which was closely related with the chemical composition, surface status, and production process such as annealing of the steel sheet.
