采用扫描电镜(SEM)和X射线能谱仪(EDS)分别对480~620℃范围内的Zn-22.3%Al、530~620℃范围内的Zn-30%Al和620℃下的Zn-55%Al(Al含量均为质量分数)镀锌铝池中锌渣的组成相及其形成规律进行系统分析与研究。结果表明，Zn-22.3%Al锌铝池在480℃和500℃下形成与由τ5和τ6相组成的面渣，在520℃形成的面渣为τ5相；Zn-30%Al锌铝池在530℃和550℃下也生成由τ5和τ6相组成的面渣，但570℃下面渣仅为τ5相。Zn-22.3%Al锌铝池由于密度低，在620℃时仅生成面渣(τ2+FeAl3)；Zn-30%Al锌铝池在620℃时除了生成面渣(τ5+FeAl3)外，中间层还生成τ5和τ6相锌渣；Zn-55%Al锌铝池在620℃下除了形成底渣τ5相以外，中间层还生成τ6相锌渣。

The phase constituents and formation of zinc dross in Zn-22.3% Al bath at temperature range of 480~620℃, Zn-30% Al bath at the range of 570~620℃ and Zn-55% Al bath at 620℃ have been analyzed systemically with scanning electron microscope (SEM) and energy dispersive spectrometer (EDS). The results show that the zinc dross formed on the surface of Zn-22.3% Al bath at 480℃ and 500℃ are mainly composed ofτ5 andτ6 phase, and onlyτ5 phase at 520℃. Similarly, the zinc dross formed on the surface of Zn-30% Al bath at 530℃ and 550℃ are mainly composed ofτ5 andτ6 phase, and onlyτ5 phase at 570℃. The zinc dross formed on the surface of Zn-22.3% Al at 620℃ are mainly composed ofτ2 and FeAl3 phase. The zinc dross formed on the surface of Zn-30% Al at 620℃ are mainly composed ofτ5 and FeAl3 phase. However,τ5 andτ6phases exist in the middle layer of Zn-30% Al bath at 620℃. The zinc dross formed at the bottom of Zn-55% Al bath is composed ofτ5 phase at 620℃. Besides,τ6phase exists in the middle of the bath.
