连续镀锌镍合金钝化的研究

Chromating of Zn-Ni Alloy Deposit

彩色显像管防爆钢带连续镀锌镍合金，对所得锌镍合金镀层（含镍量１０％～１２％）进行低铬、常温、快速铬酸盐钝化，以获得具有均匀半光亮银白色，耐腐蚀性和抗灼烧性能良好的钝化膜。

A rapid and room-temperature chromating process using diluted solution is presented for Zn-Ni alloy(Ni 10%￣12%) deposit continuosly plated on explosion-proof steel strip of tricolour tube to obtain uniform silvery semi-bright conversion coating with highresistance to corrosion and calcination.
