摘要:

目前,针对提花机选针模组工况对于高磁导性、耐腐蚀性和高耐磨性的需求,化学镀Ni-P镀层已经被认为是最适合的表面处理技术之一。 然而,国内成品药水配方所得镀层在耐磨性方面仍有明显不足。 因此,本文提出了一种适合提花机选针模组用的高稳定-强耐磨Ni-P镀层制备方法。 在主盐硫酸镍和还原剂次亚磷酸钠的基础上,仅需加入柠檬酸钠和乳酸即可得到质量良好的镀层,并分别研究了镀层与基体之间的结合力、维氏硬度和磨损率。 当络合剂调整至最佳用量时,镀层的沉积速率约为10 μm/h,施镀后磨损量较基体降低了400%。 镀层与基体之间的结合力约为15 N,镀层的维氏硬度约为1084.3 HV。 同时,通过对磨痕显微组织和化学组分的观察,发现磨痕中生成了氧化镍,通过固体润滑的方式有效降低了磨损量。 此外,通过对镀液循环性的实验验证了该方法的工业生产能力。 本文为工业化制备强耐磨Ni-P镀层提供了一条有效途径,很具实际应用潜力。

Abstract:

Based on the requirements of high magnetic conductivity, corrosion resistance, and wear resistance for the needle selection module of jacquard machines, electroless Ni-P coating had been considered one of the most suitable surface treatment technologies. However, there were still significant shortcomings in the wear resistance of the coatings obtained from domestic plating solution formulations. Therefore, this article proposed a highly stable and wear-resistant Ni-P coating preparation method suitable for the needle selection module of jacquard machines. On the basis of the main salt (NiSO4) and reducing agent (Na2HPO4), the coating with well quality was obtained only by adding two complexing agents. The binding force between the substrate and coating, Vickers hardness and the wear rate were investigated respectively. When the complexing agent was adjusted to the optimal dosage, the deposition rate of the coating was about 10 μm/h. The wear rate was 400% decreased after the coating plated. Moreover, 15 N of the binding force and 1084.3 HV of the Vickers hardness were satisfactory results. Meanwhile, by observing the microstructure and chemical composition of the wear scar, it was found that NiO was generated, which helped to reduce the wear rate. Furthermore, the recycling test of plating solution was carried out to verify the industrial production capacity. This finding has provided an efficient way to produce Ni-P coating with ideal tribological properties and looking forward to possessing anticipated potential in industry application.
