摘　　要：对预镀镍的工艺及预镀镍对重力法电镀锌层结晶形貌及织构的影响进行了探讨,并分析了预镀镍改善电镀锌表面质量的机理。结果表明,预镀镍处理可以削弱后续电镀锌过程中镀层取向对基板取向的位相承继关系并进一步细化镀层晶粒,从而提高电镀锌板的表面质量。The effect of Ni pre-coating technology and the influence on the morphology and texture of＂GRAVITEL＂ zinc electroplated coating was discussed in this paper. The mechanism of Ni pre coating improving surface quality of eleetrogalvanized sheet was also analyzed. The results show that Ni pre-eoatingcan weaken the phase inheritance of the zinc coating to the substrate orientation and refine the plated zincgrains. Thus a better surface quality of electro-galvanized sheet can he obtained.
