【摘要】 用GD-AES（辉光放电原子发射光谱）法测定镀锌板镀层中的Zn、Al、Fe的分布，看到在镀层界面上Al的富集现象，而且富集程度随锌液中Al含量的增加而更显著，认为这可能与热浸时首先生成Fe－Al相有关。更多还原

【Abstract】 The distribution of Zn, Al and Fe with depth on galvanized sheet coatings was investigated byglow discharge atomiC emission spectroscopy. The results indicate that there is a richness of Al in theinterface and the quantity of Al richness increase with Al concentration in the galvanizing liquid. Thisis closely related to Fe-Al phase produced first in the interface.更多还原
