摘要: <正> 锆极易生成表面氧化膜,对酸、碱具有极好的耐蚀性能,尤其对碱性溶液的耐蚀性优于钽、钛和不锈钢。然而锆材价格较昂贵,因此,采用电镀的方法来制备锆镀层具有重要的现实意义。锆的析出电位较析氢电位负得多,其电还原过程只能在熔盐体系中进行。Senderoff及其同事曾研究了锆及其它难熔金属的熔盐电镀,他们的研究表明锆能从氟化物熔盐

Abstract：The electrodeposition of zirconium has been studied in molten Flinak electrolyte containing zirconium fluoride.A coherent,dense deposit of zirconium has been obtained.It is shown that there are two differ- ent mechanisms for electrodeposition of zirconium,i.e.,metalliding and electroplating,which depend on the electrode material used.X-ray diffraction analysis indicates that the microstructure in the zirconium deposit appears as a texture oriented preferably along Zr[110].A lustrous coating of zirconium with a surprisingly smooth surface may be deposited on copper substrate under appropriate conditions.The de- posit is identified by TEM as an amorphous alloy of Zr and Cu.
