| 摘 要： | 针对国内生产的T5(调质度)镀锡板耐蚀性差、不合格率高的情况,研究了原板成分及晶粒度对镀锡板耐蚀性的影响.采用辉光放电光谱仪测试了大量镀锡板的表层成分分布;采用金相显微镜测试了大量原板的金相结构,并计算出了晶粒度.结果表明,原板中的锰、磷、硅和铝的存在对镀锡板的耐蚀性影响显著,耐蚀性随这些元素含量的上升而下降;原板晶粒度的增大将导致镀锡板的耐蚀性上升.

| Abstract: | For T5(temper) tinplates manufactured in national steelworks have poor corrosion resistance and high fraction defective,the effects of component and grain size of blank plate on the corrosion resistance of tinplate were studied.Surface composition profiles of tinplates were measured by glow discharge spectrum(GDS),and the metallic phases and grain sizes of blank plates were studied by metallographic microscope.Results show that Mn,P,Si and Al of blank plate have important influence on the corrosion resistance of tinplate,and corrosion resistance of tinplate will decrease as concentration of these elements increases.Increase of grain size of blank plate will result in rise of corrosion resistance of tinplate. |

| Keywords: | tinplate corrosion resistance blank plate component grain size |
