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.
