| Abstract: |
| 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. |
