Studies on plating zinc in dpe ⅲ+ potassium sodium tartrate solutions of zincate 关于DPEⅢ酒石酸钾钠锌酸盐镀锌的研究
The corrosion resistance of the coating is increased by addition of lanthanum in ammonium zincate system, but decreased for sodium zincate and zinc sulfate systems. 铵盐体系加入镧盐后镀层耐腐蚀性增强,钠盐、硫酸盐体系加入镧盐后镀层耐腐蚀性降低。
