第一段The micrographs also show entrapped rolling debris,possibly iron or iron oxide particles,resulting from the cold rolling of the strip.The micrographs also show that the uncoated bare surface of steel contains fragmented articulate matter on the surface.These particles have the general appearance of being cold welded /fused with the substrate during cold rolling.It should be noted that iron fines/particulates such as those generated during cold rolling are oxidized at the surface due to the heat generated during rolling.This ,in all probability ,accounts for the oxygen peaks observed.
第二段 In the EDS analysis of the uncoated patches.There is also evidence for iron-zinc crystallite formation (possibly zeta [fe zn 13] crystallites),indicating bath/process conditions leading to ineffective inhibition and suppression of iron-zinc intermetallic compounds.The micrographs in fig .8 exhibit the hemispherical appearance of thin zinc ribbons adhering to the bare substrate,along with entrapped matter at the interface,as well as zinc delamination from the steel substrate.The hemispherical appearance of zinc ribbons is indicative of high surface tension at the molten zinc-steel interface and the lack of good wetting of molten zinc with the steel substrate.
第三段Examination of galvanized steel specimens with coating exfoliation/peel-off also revealed fragmented particulates and a considerable amount of rolling debris on the steel surface (fig 9).The micrographs also show entrapped top-dross particles in the coating.The sem micrographs of galvanized sheet specimens exhibiting matter/dull coating appearance showed profusion and preponderance of fe-al-zn intermetallics,possibly entrapped particlea of levitated bottom dross.These intermetallics were distributed within the coating (fig.10) and conferred a lackluster appearance.In high-aluminum zinc baths,such as one encountered during the period of investigation,the bottom-dross particles (,fezn 7) that accumulate during a long galvanizing campaign become levitated and undergo.
第四段These floating-dross particles were presumably entrapped in the coating.
The SEM observation confirmed the abundance of cold rolling defects in the form of mechanical damage ,oxidized rolling debris ,and iron fines/particulates on the steel substrate.The EDS analyses also suggest the presence of burnt carbonaceous residues on the annealed sheet surface.These substrate deficiencies,together with a sensitive galvanizing bath composition,resulted in the poor wettability of zinc and consequently impaired its adherence with the steel.

第一段该镜也显示,包埋滚动碎片,可能是铁或氧化铁粒子,导致从冷轧带钢.该镜也表明,未暴露的表面钢铁包含支离破碎,阐明问题在表面上.这些粒子有一般的外观被冷焊接/融合与衬底在冷轧过程.应该指出的是,铁的罚款/粒子,例如那些产生在冷轧氧化在表面上,由于产生的热量在滚动.这一点,在所有的概率,占氧峰观察.
第二段,在EDS分析的未修补程序.也有证据,铁,锌微晶的形成(可能的Zeta [铁锌13 ]晶),表明浴/工艺条件,领导不力,以抑制和制止铁锌金属间化合物.该显微镜在图0.8展示半球形的外观薄锌的彩带坚持以裸衬底,随着包埋此事的界面,以及锌脱层从钢衬底.半球的外观锌的彩带是指示高表面张力在熔融镀锌钢界面和缺乏良好的润湿液锌与钢基.
第三段考试镀锌钢板标本与涂层脱落/果皮小康还透露,支离破碎的粒子和相当数量的滚动碎片对钢铁表面(图9 ).该镜也显示,包埋最糟粕粒子在涂层.该SEM照片镀锌板标本参展的事/枯燥无味涂层的外观显示,profusion和优势的Fe -铝-锌金属间化合物,可能包埋particlea的磁悬浮底部的糟粕.这些金属间化合物被分发涂层(图)和所赋予的表现乏善可陈的外观.在高铝锌洗澡,例如一所遇到的调查进行期间,自下而上的糟粕粒子( ,fezn七日)表示,累积在一个长期镀锌运动成为磁悬浮和接受.
第四段这些浮动糟粕颗粒假定包埋在涂层.
扫描电镜的观察证实了丰富的冷轧缺陷的形式,机械损伤,氧化滚动碎片,和铁的罚款/颗粒物对钢衬底.有关的EDS分析还表明,存在烧毁的碳质残留对退火板表面.这些衬底的缺陷,再加上一个敏感的镀锌镀液组成,导致了穷人的润湿性锌和因此受损的坚持与钢.
