摘　　要：采用直读光谱仪、扫描电镜(SEM)、能谱仪(EDS)和辉光测试仪,研究了T2硬度马口铁基板的边部氧化色差问题。结果表明:锰元素的富集与氧化是产生边部氧化色差的主要原因。通过控制基材成分、退火前板型、还原性气氛及退火温度,可较好地解决此类问题。Spectrometer,scanning electron microscope(SEM),energy spectrometer(EDS),glow tester are used to study the edge oxidation color of T2 tempered tinplate substrate.The results show the enrichment and oxidation of manganese are the main reason for its occurrence.Such problems can be solved by controlling matrix composition,plate shape before annealing,reducing atmosphere and annealing temperature.
