| 目的 改善 Ni-Zn-P 合金镀层的制备工艺和镀层的物理性能。 方法 鉴于稀土镧系元素因特殊电子结构表现出优异的物理和化学性能,向基础镀液中添加 Yb2O3,在低碳钢钢管表面化学镀沉积 Ni-Zn-P 合金镀层。 通过称量法算得沉积速率,通过盐水浸泡实验测试镀层耐蚀性,采用扫描电镜观察镀层的表面形貌，用 X-射线衍射仪检测镀层的晶体结构,考察镀液中 Yb2O3 浓度对镀层的沉积速率、表面形貌、耐蚀时间、晶体结构等的影响。 结果 随着 Yb2O3 浓度的增大,镀层的沉积速率呈先升高、后下降的趋势,镀层的表面形貌、耐蚀时间和晶体结构均是先得到改善,而后被削弱。 向基础镀液中添加 15 mg/ LYb2O3 后,镀速提高了 21. 6% ,耐蚀时间延长了 16. 7% ,镀层由粗糙、灰暗、不均匀和有缺陷,变为平整、光亮、均匀和致密,镀层的非晶相程度得到一定强化,耐蚀性能有所提高。 结论 基础镀液中添加 Yb2O3的适宜质量浓度为 15 mg/ L,该条件下可提高 Ni-Zn-P 合金的镀速,并改善镀层的质量。 |

| Objective To improve the technical process and physical property of Ni-Zn-P alloy. Methods In view of the special electronic structures and excellent physical and chemical properties of rare earth lanthanide elements, ytterbium oxide (Yb2O3 ) was added into the basic plating solution to deposit Ni-Zn-P alloy coating on the surface of low carbon steel tube. The weight method, the salt water immersion method, scanning electron microscopy (SEM) and X-ray diffracometer (XRD) were used to calculate the deposition rate, measure the corrosion resistance, observe the surface morphology and detect the crystal structure of the coating, re- spectively. The effects of Yb2O3 concentration on deposition rate, surface morphology, corrosion resistance time and crystal struc- ture of the coating were investigated. Results The experiment showed that with the increase of Yb2 O3 concentration, the deposition rate firstly increased and then decreased, and the surface morphology, corrosion resistance time and crystal structure of the coating were also firstly improved and then weakened. When 15 mg / L Yb2 O3 was added into the basic plating solution, the deposition rate was increased by 21. 6% , the corrosion resistance duration was extended by 16. 7% , the rough, grey dark and uneven surface with defects became smooth, bright, uniform and dense, the amorphous phase levels were reinforced to certain degree and the corrosion resistance ability was improved. Conclusion The suitable mass concentration of Yb2 O3 added into the basic plating solution is 15 mg / L, under which the deposition rate can be increased and the coating quality of Ni-Zn-P alloy can be improved. |
