| Abstract: |
| The work aims to design and prepare amorphous nickel-Phosphorus coatings with high industrial application value by studying the influence of the modification technology of magnesium boron silicon crystal film on the microstructure and properties of nickel-phosphorus composite coatings. The magnesium boron silicon crystal film was prepared on the Ni-P chemical coating. The micro-morphology and corrosion properties of the coatings were studied by scanning electron microscope and other equipment. Combined with the water activation characterization, the strengthening mechanism of the Ni-P coating by the modification technology of magnesium boron silicon crystal film was analyzed. Compared with the traditional Ni-P coating, the Ni-P coating treated by the modification technology of magnesium boron silicon crystal film had a great surface density and uniform distribution. After treatment, the corrosion potential was shifted by 65.6 mV, the corrosion current was half of the original, and the corrosion weight loss rate was significantly lower. In addition, the size of Water cluster treated by modification technology of magnesium boron silicon crystal film were significantly reduced and the activity was improved, which indicated that the treated water was easy to dissolve materials such as silica and boron from composite ceramics, forming a dense crystal film in the Ni-P coating and improving the comprehensive protection performance of the coating. After the treatment of magnesium boron silicon crystal film modification technology, the surface density and wear resistance of Ni-P coating have been improved obviously, which has broader industrial application value. |
