摘要:

研究了镀液配方对化学镀Ni-Zn-P三元合金施镀效果的影响，探明了镀速、镀层硬度及其腐蚀防护性，以及镀层Ni，Zn和P含量的变化规律，确定了含Zn9.50~16.57和P7.55~13.59(质量分数，%)的Ni-Zn-P镀层制备工艺。对典型试样进行了SEM和XRD分析以及耐酸、耐碱及耐盐溶液腐蚀性能测试，结果表明：镀层表面平整、均匀，结构致密，具有典型的胞状/球状及条带状微观形貌；镀层主要由非晶、微晶或其混合相组成，其中Zn和P固溶于fcc的Ni晶格中；镀层耐盐、耐碱腐蚀能力较强。

Abstract:

Effect of the bath formula on electroless plating of ternary Ni-Zn-P alloys was investigated systematically in terms of plating rate, micro-hardness, chemical composition and corrosion performance of the coatings. Then the processing parameters for preparation of the coating with chemical composition of Zn 9.50~16.57 and P 7.55~13.59 (mass fraction, %) were acquired. Typical coatings were characterized by SEM and XRD, while their corrosion resistance against aqueous solutions of strong acid, strong alkali and neutral salt was also examined. The results indicated that the prepared Ni-Zn-P coatings show compact and smooth surface with a typical cellular or spherical as well as band-like morphology. The coa
