微量鉛對電鍍鋅層織構及表面特性的影響

Effect of Small Amount of Lead on the Texture and the Surface Properties of Zinc Electrodeposit

  • 摘要: 研究了用電鍍法從含微量鉛的硫酸鹽鍍液中獲得的鍍鋅層,以及鉛對其織構和結晶形態,鍍層表面明度、光澤度、粗糙度、摩擦因數和抗黑變性能的影響.結果表明,隨著鍍液中Pb2+濃度的增加,鍍層的表面粗糙度增大,其明度、光澤度、摩擦因數和抗黑變性能明顯降低.這主要是由于Pb的存在導致鍍鋅層(002)晶面取向降低,(101)晶面取向增加的緣故.

     

    Abstract: In the electrodeposited zinc from the sulphate baths containing a small amount Pb2+ ions, the effect of Pb2+ on the texture, the morphology, the lightness, the gloss, the surface roughness, the friction factor and the black tarnish resistance of zinc deposits were investigated. The results show that with an increase in Pb2+ content in the baths, the surface roughness of the deposit was generally increased, but the lightness the gloss, the friction factor and the black tarnish resistance were generally decreased. It is primarily caused by a significant change in crystal orientation of deposited Zn, due to Pb2+ ions added in the baths.
